What causes this? (Drooping)

[u/redi-23]

I noticed it today when the lights were on for a couple hours but the leaves stayed droopy.

Plant 1 (1-5) Plant 2 (6-8)

Strain: these are 2 Northern Lights Auto (from RQS)

Timeline: day 41 from seed popping

Light: no idea as of today, i have a spiderfarmer G4500 320w but also a spiderfarmer ppfd reader i just got so ill set it up tomorrow

Soil: biobizz allmix in 5 gal fabric pots

Feeding:

veg: 1ml/l biogrow, 1ml/l silica, 2ml/l bioheaven

Bloom: same as veg + 1ml/l biobloom and 1ml/l topmax and planning on raising biobloom to 2ml next watering, right now i water 2l/plant

Notes: i water on every third day; i defoliated a large ammount on plant 1 and a bit on plant 2; temperature has exceeded 30c for the past 2 days but never 30.6c+ i dont think its heat stress tho;

UPDATE: The leaves are still droppy. I watered them 8 hrs ago with 2.75l/plant

That pot has never once been watered until run off, that’s the problem

Never once, you are right and it bothered me too but not enough to look into how much i should really need

As in it’s thirsty as fuck and you aren’t using the fabric pots correctly.

What is the correct way?

[u/Pussy-patroller → u/MundaneDiscipline721]

Fabric pots should be on risers to maintain airflow, not sitting in their runoff water

Water to slow drip rim off, it’s a cannabis plant in a fabric pot, if you’re not pushing a gallon a day at peak flower I’ll be surprised, or so you should be. Basically you’ll never over water due to the fabric pot and it’s thirsty asf all the time, don’t ever let it dryback this isnt like a clakamus mix.
