Overwatered or too much light?

Hey man, sorry to see another issue, but it's what makes us better growers. How have you been watering? I ask because it could be waterlogging by the looks of things. If that's not it. It may be a deficiency of some type. Maybe ph issues locking out certain nutes? I would explore the watering option first, though.

Wondering about P defficency. For The watering i was using water at 6.4ph and each second watering i used with nutes. Wondering about quantity of water cause i used about 1 liter for each plant and yes There was not much runoff. My fabric pots leaking on sides when feeding i always try to make water run out from The bottom. Maybe too frequently and not much like 1 liter. Soil was dry after 2-3 days. I will try to use more water and less frequent next time and i will use full dose of nutes.

Yesterday My girlfriend soaked all plants in Basin with water to let them suck from The bottom (like autopot system) cause she also noticed that water run from sides but dont know if this was Good idea. Hope They dont die untill then i see that they have potential to give nice amount of weed.

Ok so i have checked and i think its Phosphorus deff so now when i watered them yesterday i need to wait for dry out ? Im scared about more progress with P deff untill next feed; this time with nutes on full dosage or PK booster 13/14 from Canna.

You may also try lowering the ph. I am hearing that some 'soils' actually prefer a lower ph closer to 6.0. That may be locking out the phosphorus also. But if you are sure it's not watering issue, then yes, add a bit more PK, but I would lower the ph also. Again, not a soil expert, but this is what I would do.

Now they look fine no droopy leaves so i think Its not overwater but P deff and also Cal Mag. I'll post results in few days after feeding. I think tuesday will be ready-to-feed day.

Not so quick still leaves arent praying, now i will do 2 things rise them a bit from 21 inch to 24 maybe more and change to 18/6 from 20/4 maybe stress caused by lst, topping and problems with induction to flowering (propably caused by hermie wich grown over 1 month with them wich i removed after seeing polen sacs) making them tired too much so they need more time to rest.

And look at this bottom leaves are curled up and crispy....

That may not be the light. You should rule out an environment issue first, specifically high temps or low humidity. What are those numbers for the typical day and night?
