3rd Grow - Time For The Light Show

Great catch regarding the idea to vent through the chimney. This should work out great but there could be an issue with this.

When Xmas morning rolls around you may find ole' Santa partaking in some of the fruits of your garden and may not be able get the fat bastard to leave if he gets a good taste. I'm sure he's like most of us and would prefer some dank buds to cookies and milk. :blunt::yummy:
 
My stomach just growled at me.

No matter how much I like Santa he can keep his grubby mitts away from my garden :)
 
I have some pictures, am still having problems uploading to the site but as soon as I use a VPN they upload fine. The moderators are looking into it (thank you mods) so hopefully some conclusion will be reached soon.

Here are some pictures of how the girls are doing and the temps in the tent. Still not as cool as I would like but much better than the 35C+ that was showing yesterday:

I'm thinking that they may have indeed been overwatered as they're a little droopy so they have not had a watering today. As they have been in the soil for almost 3 weeks now I'm thinking that after a light watering tomorrow that I will feed some nutrients. Would this still be too early? I don't want to leave them for too long as I have seen what happens with that on arellanobrians grow and the plant never fully recovered. What do you think fellas, too soon or is 3 weeks since they sprouted enough?

All the best :thumb:
 
Since you're growing in a composted soil type grow medium there should be adequate nutrients available in the soil to keep them good and healthy until they grow a bit more. If you're watering with tap water there are some additional minerals, although in minute amounts being added every time you water.

IMHO when growing in soil it's best to either not feed or go very light on any nutrient or fertilizer applications until a bit later in the growth cycle. It doesn't take much to overfeed and cause problems with a young plant.
If there are any nutrient deficiencies present your girls will let you know it by showing you some signs such as leaf yellowing, spots, leaf curling, etc . Judging by the pics all appears to be going well.

If you do begin feeding nutes I suggest feeding at half to one quarter of the recommended dosage until the girls get a bit bigger.

Best of luck bro!
 
Thanks UncleCannabis, it's mainly the LSD that has me worried as the lower leaves are still browning. The soil is just bog standard 400litres for £15 so I'm not expecting too many nutrients out of that. I specifically checked that it wasn't one of those soils that promises to feed plants for a month or so as I wanted to have control over that too.

I'll have a chat to the girls tomorrow and see what they're thinking ;) . All the best mate and I appreciate your help :thumb:
 
Agreed. Keep it light if you start feeding. If you think you over watered the plants, give them a couple days to dry out. The roots will grow trying to find moisture and the plant will end up bieng healthier. Don't want to keep watering so often if they keep telling you not to.... every 4 days should be plenty for a while. When they start packing on nodes you could water more often. Good luck!
 
Ditto what guambomb said about watering.
It's good to let them dry out a bit so that the roots penetrate down toward the bottom of the pot. If you water to heavily and keep the medium too wet the bottom 1/3 of the pot will become water saturated resulting in oxygen displacement.
Any roots that may be present in the area will experience fungal problems or root rot. If no roots are there yet they will never penetrate down into the waterlogged portion of the pot.

During early life of a seedling or anytime that I transplant I like to give a heavy watering, let the medium dry out a bit, follow with a light watering, let the medium dry out, then go with another heavy watering.
This will encourage healthy root growth and get the roots well distributed throughout the pot.

After taking another look at your girls it appears that they may be showing some very early signs of deficiency.
Notice the leaf veins seem to be a bit darker color with the leaf possibly yellowing slightly.
I wouldn't worry just yet but before attempting to address a possible deficiency do you know what your soil ph is?
 
I have no idea what the soil PH is and I'm not sure how to go about testing it. Would I just test the runoff? I think if I made a muddy solution to test it might just mess up my PH meter.

I'm really happy that you posted the last part about the slight signs of deficiency, as I hate to go against knowledgeable advice but my gut instinct on this was that I really need to give them a little feed tomorrow, they seem to be crying out for just a little something. I'll give them a light watering and then a light feed an hour later if that's the case. Thanks again and all the best :thumb:
 
IMHO it's critical to know what your ph is running throughout the grow. Your soil could be packing all of the nutrients your girls need but if your ph is not between around 6.2 to 6.5ish some of those nutrients will be not be available for your girls to take in. Ph lockout.

Because you mention that your soil is bog standard I'm assuming that it may have a high peat content which could make is very acidic.
If this is the case and ph has not been adjusted then I'd venture to say that your soil ph is probably in the 5.3 to 6.0 range which would cause nutrient lockout.

To test with your ph pen you'd want to first calibrate the pen. Then mix 1 part soil to around 5 parts water (water with ph 7.0 is best). Let it sit about 1 hour then filter through a paper towel or coffee filter. Then go ahead and check the reading with your ph pen. If your ph reading is below 7.0 this would mean your soil ph is less than 7.0 acidic. If your reading is higher than 7.0 then your soil ph is above 7.0 and alkaline.
The rule of thumb that I was taught long ago was to add or reduce by 2 tenths of a point depending on if you end up on the acidic or alkaline side of the water solution that you use to mix the soil with.
For instance, lets say the water that is used begins with a ph of 7.0 and your ph reading comes out to be 6.8 when reading the solution after mixing with the soil. Then this would mean that your actual soil ph is about 6.6.
If your ph pen is reading 7.2 then this would equate to a soil ph of 7.4.

I hope this is not too confusing. If so, there are likely some threads on this site which would provide better instructions. There may also be a better method than what I've explained.

Bottom line....ph is very important.
 
Easiest way to test soil ph is to get a pool ph test kit and put soil in the test chamber, add solution and shake. Then match the color of the liquid. I have never done it personally, but have seen several people do it. Hope that helps. Also you can test the run off and get a pretty good idea. If what you put in isn't what you get out... adjust till it is.(Edit - when they get bigger:) ) Hope that kind of helps bud.

Edit- I like U.C. method better. Costs less :thumb:
 
I would really encourage you to let your soil medium dry out a little before giving them any more water or feedings. What you're seeing could be a result of the over watering and not due to a deficiency or ph lockout.
If it has been determined that you were indeed over watering (only you know for sure) then just stop watering and monitor.

Problems take time to work themselves out. If you try more than 1 cure at one time you'll never really be certain what the problem was or is and will end up addressing the wrong issues and will do more harm than good.

Basic Steps for Moving Forward
1. Do your best to determine the most likely reason for whatever problem may be at hand.
2. Do your best to try to determine the best solution for the problem that you're about to address.
3. Give the selected cure a try then wait and monitor.
4. Monitor new growth more so than the previously damaged leaves. If you've identified the problem correctly and have given the correct dose of cure you'll begin to see improvement in the new growth turning back to what should be normal condition. Old damage may not recover no matter what nutes are added.

Anyways, I hope this helps bro.

In the meantime I'll be out of pocket for a few hours. I'm about to go and introduce my last 3 girls the guillotine then I'll be busy trimming for a few hours.
Feel free to PM me if you have any questions and I'll get back to you later when I'm able.
 
My 1 1/2 cents. I doubt that your plant's soil is lacking nutes at this point. That is a lot of soil for those little plants, and I think there must be enough nutrition in there to sustain them for at least another week or two. I think if there is a deficiency it has more to do with pH. At least – this is how I would treat it if it was my plants- for better or worse.
Also (the remaining 1/2 cent) -those little plants in big pots have to really be babied when it comes to watering. Like- I wouldn't go soaking one down to test runoff. I'd just pussy foot around trying to moisten the soil without overdoing it- till they get bigger.
 
I would really encourage you to let your soil medium dry out a little before giving them any more water or feedings.
And 2 things to add to that; if you're feeding before your soil is dry there's no need to pre-water, and if there's a lock-out, letting the soil go completely dry (if there's a lock-out it'll take awhile) then watering with plain Ph adjusted water is the quickest route to recovery.

I know we're throwing a lot at you at once but it's all correct and makes since. If you look at it like a parking sign totem pole the way you have to read from the top down to see if it's a good parking spot you'll get it. Read each post one at a time and each piece of advice that you think applies footnote it. Then let us know what you come up with for a plan of attack.
 
Ok fellas I've just woken up and read all your advices and I'd like to thank you all for that. The thing is I didn't think the plants had a problem before I went to bed and now they're already fkin doomed :rofl:

I appreciate the write ups on how to test my soil so +reps for that and I also appreciate the advice regarding not feeding. The problem I have here is that I have a feeling that the girls want one and it has been 21 days cotyledonageddon so I think I'm still going to have to ask the girls about this. Please don't take this as a slight to your knowledge or see me as disregarding your advice it's just that when I'm sat in my tent with the girls this is the feeling that I get. It's a decision that only I can be responsible for and if it turns out to be a bad one then I only have myself to blame.

So this my order of the day today, will use UncleCannabis' how to on testing soil, then sit and chat to the girls for awhile and either feed or not after that. If it all goes to shit well, what's new on one of my grows? :)

All the best everyone, feel free to shake your heads at the noob grower but please don't let it put you off posting all your great advice, it really is appreciated even if I may have to go against it now and again just to prove to myself that I can fk up a perfectly good grow with gut instinct :thumb:
 
OK so I went and had a chat with my girls and they are indeed feeling a little peckish so I'll be feeding them a little something later (sorry guys but ho's before bro's I believe your saying is? lol), not meaning to be a dick though it's all tongue in cheek, honestly my LSD is screaming for my attention. She will be the one that I feed today, the rest are ok if a little dry.

This is the LSD, she is demanding my attention. I've tried a different view to try and show you all what I mean:

I also decided that as the plants were all straining to wards the CFL that I would use the 1600w again. The CFL is a great light for smaller pots but it just doesn't have the coverage for these sizes, something that I'll need to bear in mind in the future. So I'm going to see how they are with the big light, kind of wasted but maybe I'll turn the Reflectors off for now if they respond well to the 1600 this time.

Also I have set myself some soil soaking for a PH test in the next hour or so. My pen hadn't been used for awhile and first read PH6.8, then PH7.1 on my PH7 buffer solution, I wasn't impressed but after the three initial calibrations it did decide to play nice. It was working steadily until I left it unused for awhile, let's hope that it's just a peculiar quirk that it has:

Calibrated:

The amount of soil I used (all very scientific here):

The amount of water I added:

IMGP11192.JPG



Now it's just a case of time. I'll be waiting an hour for the soil to mix properly before filtering it and testing. One question strikes me though, if I filter through a medium will it affect the PH reading or is that what the +/- .2 difference is for?
I'm pretty sure my kitchen roll is bleached, so it's just a question that occurred to me, I'm not going to worry about it too much for now though. I'll be back later with an update (Have to love having a nice lazy Sunday where I can get things done as and when I want). I hope you're all having a great weekend everyone. All the best :thumb:
