maybe get us a lights off pic. they look a bit dicey to be on the leave. i'm seeing hunger at the edge.

also have you flipped ? if you have you're right at the point where stuff is crucial. you better have someone familiar with the set up and on point, cause they are fixing for a big ask and nute re-balance by the looks.





go no bigger than 5L. avg washroom wastebasket size. do not put the hole higher than 2 1/2 inches from the bottom. i prefer 2 1/4 to the middle of the hole.


a 5L produces about the same as a 5gal soil or hp grow.





5 gal is 20L. 25L is about where i'd run start to run outdoor monsters. there's no way they are getting a proper dry cycle in those indoor. that's why i'd recommend running an enzyme cleaner or h202.

I'll be gone by the time the lights go off tomorrow, leaving around 2pm lights go out at 3pm.

They're autos bud, at least they're supposed to be anyway. They're roughly around 54 days old.

I upped the nutes on last feed to around 1100 ppm's. They will be getting fed again in the morning before I leave.

I'll get some 5L buckets then. I'm going to guessing with those buckets I'm using thats more than likely a big contributer to the higher humidity I seem to experience in the tent.

Here's some more pics of how the plants look at the moment.

With one light on dimmed, flash on.

With both lights off, flash only

Thanks again for the reply and help.

if you have flipped and won"t be back before next feed : calculate and premix your next nute bump.

I've taken that into consideration and upped the nutes slightly on their last feed, I will be feeding them in the morning and mixing another batch for when I'm away aswell.
Once I'm back I can also give them a flush with some h202

 

[bluter]

looks like you have it well in hand. there's gonna be a pk ask soon. look ready to trigger.

You can get 5, 2.5 & 2L paint kettles in Wickes and B&Q cheap mate. Or pound shop for small waste bins. Think I'm gonna get the 2.5L ones from Wickes for my photo grow. £1.50 each.

Sorry for the late replies.
@bluter
Not long back from my vacation, place was in the middle of nowhere and couldn't get a mobile signal so was unable to access the internet, reply, text etc.
Plants look ok, on one of the plants there's some leaves with some rusting like spots on them but other than that they seem to be in good health. I'll get some pics and get them posted ASAP and maybe it would help with a diagnosis.
I'm thinking I might give them a flush on sunday aswell. I have the little one staying for the weekend, I try not let her see anything where the plants are concerned so Sunday would be my best bet for flushing the plants.
I have 12% hydrogen peroxide there.
What would you recommend I dilute it at ?

Thanks again.

Thanks for that mate. There's a wickes quite close to where I am so can always take a trip there to see what buckets I can get. There's a few places I've seen online that sell black buckets quite cheap they do 2.5, 5 litres upwards and are reasonably priced so can have a look if I can't get anything more local.

Some pics of the plants now.
The lights went off around 50 minutes ago so there's a bit of droop but they looked fine, no drooping when I checked on them around 11:30am.
I put the light on for a few mins to take a few pics so the rusting spots are visible. It only seems to be on the one plant, the biggest plant. The spots look similar to last time, which was a magnesium deficiency but i would rather ask for advice as to what it is and how to treat it given that the plants are a lot further along than last time.

 

[InTheShed]

Looks like a calcium deficiency to me but I don't know anything about flushing coco with H2O2 or why you would. There shouldn't be any stored nutes in coco since it's drain to waste, and H2O2 is used to kill root-rot or fungus gnats, neither of which you have.

With every feed the plants have been getting the recommended 2ml per litre of sensi calmag xtra. I was told that calmag is needed with every feed in coco.
It was mentioned giving the plants a flush with h202 previously.

Would you recommend just a flush with water ? What about dealing with the calcium deficiency ?

 

[InTheShed]

Are you watering to runoff every time? No reason to flush coco if you do. Just make sure to pH to 5.8 each time.

I'd bump the cal-mag and see how it responds.

Not sure why the H2O2 flush was recommended so I'd tag whoever mentioned it.

Yes. Every feeding there's at least half of what's going in coming out in runoff. I basicly fill that green tray next to the plants at least once per plant.
The res is quite big with the plants being in 25L buckets.

I've checked the pH but haven't been adjusting it for the past month with using the advanced nutes pH perfect. The main issue before I believe was due to feeding the plants in coco without using calmag and they started showing signs of a magnesium deficiency because of that.
I contacted AN and was told I needed to use calmag with every feeding in coco and not to adjust pH and over that time since adding the calmag I haven't really had any issues.

I tagged them about 3 posts up asking for advice, they've helped me many times in the past and have always given me pretty solid advice, same with a couple of other members on here.

#497 it's mentioned here by bluter.

How much would you recommend i bump it by ?

 

[InTheShed]

I would make sure the pH was ~5.8 just before you feed the plants and only water to 10% runoff to save money on nutes. And I'm not sure why bluter recommended H2O2. He seemed to think your pots wouldn't dry out given their size, but those are some big plants. How often do they need water?

I'd go to 3ml/L and see if it progresses.

I can check the pH and adjust thats not an issue, I have pH up/down there and a pH pen but have found in the past with changing the pH with those specific nutes it seems to want to float back up/down to whatever it was at previously.
It can be hard to gauge at times exactly how much the plants need with the pots being as big as they are and the coco always soaks a fair amount up before theres any run off.
I've seen me giving them anywhere between 4 and 7 litres each per feed.
AN nutes say to feed every day in coco, I generally feed them every second day, occasionally if I'm being lazy I'll feed on the third day but its not that often I wait until the third day to feed them.

 

[InTheShed]

It can float in the res but you should pH it just before you water. And how do you know when it's time to water the plants? Do you lift or tip them to see how light they are? That's the best way to tell.

If the pH floats in the res is that going to cause a major issue ?

I normally do both, lift and tilt the buckets. If they're too heavy to lift upwards I'll tilt them and check to see when I get runoff. Further I can tilt, I would assume the emptier the res will be. I also check the top of the coco for moisture but I don't use that as an indication that they need feeding, just something I've got into the habit of doing every other day but even when the buckets are quite dry they're still quite heavy being 25L, filled with coco, perlite and hydroton pebbles.

The plants could probably go 3 days between feeds but just not sure how that would impact the plants with the label claiming that the plants need to be fed daily in coco with those nutes.

 

[MGD420]

Back left, biggest plant is 30 inches tall from the coco and 2ft wide and they're only really starting to produce pistils now.

When the plants get the water, it should go in at 5.8 no matter what it floats to in between.

Okay, I'm a little confused. Are these sitting in water and your bottom feeding them? Where is this reservoir? I apologize if I missed the explanation.

I'm talking about the pots themselves being light, not the whole apparatus!

with the label claiming that the plants need to be fed daily in coco with those nutes.

They don't know your plants, mix, or how the reservoir system. If the pots are still soaking wet there's no need to soak them again.

The buckets have a reservoir at the bottom same as with hempy, except I'm using a coco/perlite mix instead of perlite only. When i feed the plants it fills up at the bottom of the bucket until the water runs off.

I think this is why @bluter mentioned the plants wouldn't really be getting a dry cycle and suggested a flush using h202.

check the bottle. i use a 2-0-0 product and it recommends up to 5ml per gallon.. different amounts at different stages.
you probably won't need that much but you should bump it. you have to feel it out for yourself.

It was mentioned giving the plants a flush with h202 previously.

it's a lack not an imbalance or lockout.

I've checked the pH but haven't been adjusting it for the past month with using the advanced nutes pH perfect. only. When i feed the plants it fills up at the bottom of the bucket until the water runs off.

that's gonna bite you in the ass. those are awful nutes for most applications.

adding calmag is gonna change the ph. it messes with the ph balance with that particular AN line. unfortunately you will have to live with it or change the nutes. it might get super dicey in flower.

ph is job 1 in hydro. if you don't control it you won't like what does.

I think this is why @bluter mentioned the plants wouldn't really be getting a dry cycle and suggested a flush using h202.

i run one periodic to keep the plant healthy or to correct a lockout.
you could run a bit constant to kelp keep the res and root zone happy as it doesn't get a dry cycle. the res is a bit big.



now is when to start a booster. they are going to be tossing a pk ask soon.
