See , u learn more here than college.
Who needs college in agriculture
LMAO

well I flushed my plant really good. so we will find out about turgidity, lol

You'll be surprised how it perks up. As far as feeding goes, remember that soil has food in it. When you transplanted you made a whole bunch more food available to the plant. If you weren't watering well, you weren't giving the plant what it needs to move nutrients out of the soil. That is why you are seeing some signs of slight deficiency, probably, not because what the plant needs isn't in the soil.

When my plants need watering, they are very quiet; when they are well watered and fed, they are singing!

Sorry to interrupt you Jam but it's time for someone with an unresolved issue to post:

THE CANNABIS MYSTERY OF THE WEEK​

Here's last week's.









Now who needs assistance?

Welcome to Cannabombs "Mystery of the week"


I am growing a Northern light Automatic in soil.
The soil has a Ph of 5.5-7 as stated on the bag.
The plant has been great with explosive growth up untill 7 days ago.
I started my seed on the 13/5/14
Problems started showing half way through week 5.

It all started when I changed my Fertilizer, I had read that you are to always check your PH before giving the plant its food, as I use powder nutes that get sprinkled over the soil first, I could not do that, so I went and got some basic Tomato liquid nutrients.
The liquid nutes have a NPK rating of 3-1-5 and also contain trace elements. The bottle says to use it once a week but it says nutrients remain active and usable for 2-4 weeks in soil. They recommend 10ml per liter.

On the 18th of june I gave the plant 10ml of fertilizer with 1.5 liters of water, I did not check the P.H going in, but after I saw this problem I made up another feed of 10ml fertilizer and 1.5 liters of water tested the PH.. the water was so dark I could not see the PH drops doing anything at all. If anything it looked like my PH was 3-4
This was the first sign I saw, it happened very fast within 24 hours.
The markings were only on two leaves, and it was the last two fan leaves on the top of the plant(the main cola or top)

So on the 21st, Three days after giving it this fertilizer the problem started getting worse and I was advised to flush the plant, which I did.
I checked the run-off after 30 mins of flushing and it was still coming out at 5.
2-3 hours after the flush the plant showed dramatic spread of the problem it seemed to move across all the tops in a matter of hours, the problem was much more spread out and not so much direct damage to one leaf, they all had a spot or two and all looked alittle greyish..

I let the plant dry for two days and on the 24th I gave the plant a very light feeding of my old nutrients.. they have an NPK of 10-6-10 I gave it half a teaspoon and sprinkled it over the soil and watered, I checked the PH and it was still sitting under 6.

On the 25th the problem seemed to stop spreading but the already affected leaves seemed to be getting worse.

On the 26th being today,
I flushed the plant for another 30 mins and I was not going to stop flushing untill my PH went back to 6.5 it took about 20 liters of water till the run off stopped coming out orange and more clear like water, checked PH and got a rough 6.5 that was roughly 12 hours ago and now the problem seems like it has started to spread again, now almost all the tops have been affected.

There is not alot more to say, I am hoping the pics can explain abit aswell =)

If you look close you can see that every leaf that is light green has been affected in some way or another, some leaves also have bluish grey patchs not brown, the main steam also has red lines running up...

Thanks alot for reading and helping me so far guys, I am sure it gets annoying have newbies always asking question you have answered thousands of times, I really appreciate the help that I have had, from buying my light to buying hydrogenperoxide for fungal gnats its great to find like minded people in a place that isnt full with big heads and people just being A$$ holes all the time =)

Ask for anymore info and I will do my best, and please if I just need to chill out and stop worrying tell me, I would love to hear that =)

The pics dont do the problem justice, it looks quite abit worse in person =/

Your leaf damage appears to be a phosphorous and potassium deficiency I believe was caused by pH lockout due to fertilizer buildup in the grow medium and low nutrients caused by flushing. Do you have fungus gnats in your soil? Fungus gnats can destroy your plants and cause many different deficiency in the plant due to the heavy amount of root damage fungus gnats cause.

"Tomato liquid nutrients.
The liquid nutes have a NPK rating of 3-1-5 and also contain trace elements. The bottle says to use it once a week but it says nutrients remain active and usable for 2-4 weeks in soil. They recommend 10ml per liter."

The tomato fertilizer you are using is not appropriate for container gardening with every watering. I would purchase a different fertilizer if you plan to fertilize every watering.

You want pH 5.8 for hydroponic and soiless (peat moss and coco coir) and pH 6.5 for soil.

I use General Hydroponics Flora series 3 part nutrients that can be mixed for all stages of vegetative growth and flowering. General Hydroponics Flora series can be used with hydroponic, soil and soiless mediums.

For soil insects I use diatomaceous earth on top of the soil as a barrier, it cuts them as they move through it. I bought my diatomaceous earth from an animal feed store, do not use the type meant for pool filters. Mosquito dunks can also be used as a soil drench for fungus gnats. Sierra Natural Sciences also makes a soil drench called SNS-203 for fungus gnats and other soil insects.

Oh, and the website is behaving like it is my first time here. All back to the beginning of each thread and I am not getting email notification of posts. Is anyone else experiencing this?

There is a known bug that can cause email notifications to be lost, if this problem applies to all of your subscriptions I would report the problem to this forum.

THE CANNABIS MYSTERY OF THE WEEK​

A few more pics showing the issue a little better may help Hawk.

mystery question 1

Hey experts, lol

ok I got one plant. that has a lot dry leaves on them. some were on bottom which I know is normal some leaves will die. but I noticed
in middle of plant and few places on top were dry looking also. humidity is 40-50 temp running 71-72 atm.
plant is sucking water like crazy. im to watering every day seems like it. from 1 1/2 - 2 days watering.

anyone got an idea why im having few dry leaves in veg stag. I have about 2 weeks before flowering stag.
im using no nutes in water atm. but I did run some last week. can that be cause of it.
or is the plant telling me to put in flowering stag.

there is no spotting on plants nor discoloration. nothing wrong with leaves. but they feel n look dry.
here are some photos. some need veg growth so show. color of leaves.

here is healthy plant beside it under same lights. to prove its not heat or lights. drying them out. even fan going inside 24x24x 56 darkroom

Cfls red and white. 5 reds. 1 white light with. 3 - t15 on lower half of plants.
And this is the second grow with same set up. haven't changed anything.

one beside the dry one. ,it cant get anymore healthy

this beginning of the dry syndrome.

next stage

third stage

final stage of dry syndrome

I believe you are watering improperly, your humidity is too low in your grow area and possibly your soil has too many nutrients due to the addition of green sand. When you water you want to evenly saturate the soil so that the plant has several days of water and nutrient. You want to give the soil several days to dry before watering again. I would purchase a cool mist humidifier for to place either in your grow area or the area where you intake the air from. You want 70°-90° Fahrenheit and 50%-70% humidity for vegetative growth and 30%-50% humidity for flowering. FoxFarm Ocean Forest soil is known to be high in nutrients without the addition of green sand. If you have not already done so I would flush your pot with at least twice the volume of pH adjusted water as pot size or until your runoff water is pH 6.5.

 

[Grayhawk]

well I think I found the issues. there are more than one here.

First yall are absolutely correct on watering. not enough water. and I do believe some of the chemical burn as well.

But. here is one of them main problems I just found today. temp is 86 degrees.

so not only watering, plus mild nute burn, but heat stress, also.
and here lies the root of the problem. ME>not knowing and learning as I go.

but I shall get there. I hope.

thanks ladies and gentlemen your help is much appreciated.

 

[KingJohnC]

If your highest temperature is 86° Fahrenheit that is not a problem with sufficient watering.

Hey my friend
you are doing great ,,, you seem to have the problem solved sorry I couldn't be of help but with the right attention you will get there and there is nothing better than harvesting your own med,,,I think like you it may have some slight nute burn but from what I have read the whole can be sorted out and great to have you here on 420

 

[jaamzhow]

This is such a great forum, always get good info and answers.

 

[trichomes]

no way that girl is still on the fire escape today, did it rain? is it breezy over there today? any DCS points recently?

LMK if you'd like more questions, I have 2 more for you,

& about your weather, this may help

 

[B A R]

Hello Trichster. Yes they're still out there. No it didn't rain nor was it windy, in fact it was a picture perfect day & there wont be any attempts to retire from the DCS in the near future. With the 7 rescued STREET GIRLS & the BUBBLE GUMMER seedling the show has been over-booked.
I know you're not telling me to bring my Fire Escape girls inside with that beast you have outdoors? LOL...

 

[trichomes]

YOU KNOW IT! I thought you would have the edge of that storm, I'm glad she's out there in the elements with the street girls close by.

I'm glad you finally got some cuttings to root for you, but don't retire the DCS just yet, maybe you'll let me store it for you,

I may need it in my yard. I will return it, when I see a root.

BTW, I'm

emoticons may have helped with your cutting that did enter the DCS PROOF HERE?

 

[scottish]

Hit an issue, I think it's hungry for nitrogen?

 

[Spimp]

Nah. I replied on your thread.

 

[b.real]

I think your plant is naturally defoliating some leaves.

 

[scottish]

Lol that's what spimp said on my thread as well and normally I would agree but the 3rd n 4th pic are at the top of the plant I have just stripped the dying stuff off and not going too feed I want a variety of opinions but she is nearing 4weeks and the fastest growing plant in the tent

 

[Cannabomb]

Thank you you saved my plants life!!!

I posted a week ago with major problems, and had some of the most amazing help on hand, my plant has taken a beating but has pushed through and still budding up. So thanks for all the adice guys...Here a few updated photos from today

Northern light autos
Day 35 of flower

Day 10 of flower

These photos might be upside down and inside out sorry in advance =)

 

[b.real]

those flowers look great. which light did you use again?

 

[Cannabomb]

Mars II 400w, Sensi Seeds Northern lights, worst fertilizer on the market, bad Gnat problem,Nute lockout/Def/burn and a stoned grower = this?? Marijuana your awsome x

 

[b.real]

that's impressive for a light that draws 170-200 watts. how far away from the canopy did you keep the panel? if you defoliated your plants you wouldn't have gotten those awesome pyramid shaped buds that you have forming.

for your next grow you could try incorporating some techniques like lollipopping 1-2 weeks after the stretch. all you do is pluck the "sucker" buds from the bottom of the plant so the energy goes to the tops.
