Hi guys, i have been growing for a few years now, always Hydroponics (DWC, IWS)
1st time i have ever done coco, i am having a little trouble (think possibly over watering)

So i have 10 plants all together, 6 are in 11L rhizo (fabric pots).
Other 4 are in dwc.

1 x gavita pro line 1000w light (running on 750w)
1 x 600w light (running on 400w)
Room temps with lights on 24c-27c
Lights off - 17c-20c

Humidity with lights ON - 40-48%
LIGHTS OFF - 50-60%

Good air movement with a big fan and a good outtake

Nutrients are all shogun:
Katana roots
Hydro grow A & B
Silicon
Zenzym
Plant magic calmag

PH - 6.2
EC 0.8 - 1.0

They've been topped and super cropped and was fine after

Hand watering 2L every other day

The plants are now drooping and leaves curling inwards

Any ideas?

That's not from over watering. Plants that size in coco should be watered daily. You do not want the coco to dry out and you do not want to give plain water. Looks like a nutrient issue. See it all the time with people using a bunch of bottles of cannabis specific nutrients.

It could be something else. How close are you're lights? I'd lower the pH to 5.8 - 6.0 as well.

I don't think it's nutrients, i think im either over water or underwatering them, i did think over but now people got me thinking underwatering?

I have a plant that is curling inwards like that.. I'm using pure coco, no perlite. Maxigrow, tap water ph'd to 5.8-6.0 ..
Also have a clone of the same plant in flower and its doing fine.
You can't over water in coco.. Ive drenched my plants before and they're fine.

what confuses me is I didn’t think you could overwater coco as long as it had enough perlite unless it was just drowned in water however that crazy leaf shape reminds me of plants that are either being overwatered with tons of nutes or being beat down with an intense led

and @SoD4nk thats from to much light

That’s why I hate speaking in definitives lol I’ve always heard a lil tacoing is good but when they start to roll over on itself the light was too intense causing the plant to try and shade itself now I’m curious :confused: I’ll watchi for the resolution lol

It's not a matter of how saturated the medium is........it's how much oxygen is available to the roots.
Coco retains 30% oxygen even when completely saturated.
The roots are completely immersed in water in DWC, yet they thrive because of available oxygen.
