Overwatering?

Hi all

It's about week 8 for these plants. I was feeding them once per week w/nutes. 450W Led's "30 above canopy at %70 light strength. The temps are 26-30C, %65 humidity on average

Its probably overwatering...if so what can I do from here? Just leave it and pray they recover?

Thanks

Another suggestion (I have my tent closed up at all times in a pretty musty shed, few windows open) if the plants aren't getting enough fresh air and too much carbon dioxide would that also be the reason my plants dropping like this?
 
Looks like it could be your light is too close or they are thirsty. What method do you use to determine if they need to be watered? Looks like your medium is coco/perlite? Indica dominant strain? What humidity and temperature are you growing at?
 
Well they sure look dry now. Do they perk up after lights come on do they seem to reach for the light leaves turn upward? How often and how much water do you give them? Are you wetting the whole pot slowly getting the edges wet? Is there any fan blowing on them?
 
I feed half em yesterday with straight purified water to test if they would come back up ( I only mist sprayed a little bit) now they sagged worse than before. With determining if they need water, I only feed them once a week as they were healthy as, I was hearing you don't want to leave soil to dry for too long, and it was working for 4 weeks no issues. Yeah the soil is canna terra professional Coco/perlite %85 organic. Humidity on average was %65. Temps are ranging 26-30c. I'm not entirely sure what strain I think it's Bcl XXL critical, or something like that
 
No for the past week or two they have slowly started to droop. I feed them once a week and use a 2 litre spray bottle to feed them ( I probably only use 1-1.5 litre spread out to ten plants). I spray all around the top soil, trying to cover all the soil. Yes I got one fan on rotation at all times
 
Yeah I'm at a loss. It's annoying how one site says leave ur lights "24-30 above canopy at %80-100 then another saying it's better for led to be "36-48 at %60-80..I think I'll raise it to "40 above and have it at %60...idk...where it sits currently, no leaves are curling upwards or any signs of burnt leaves expect to very bottom leaves
 
I feed them as normal last Friday, they weren't picking up and feed them a little bit again two days later. Left it until yesterday where I feed them tiny bit (no Nutrient clean water this time).
 
30⁰C is a bit hot at that stage. Aim for 25 if you can with lights on and about 3⁰C lower of a night. In soil watering once a week at that stage should be fine but if it's a bit hot twice.

They will pick up. I suspect your roots are too hot. Not nute wise, temp wise.
 
You might have to water more in air pots.

I think small soil grows in airpots could be challenging.
 
Appropriate distance from light to canopy varies by light. Follow the manufacturer's recommendation for light height, then watch your plants and adjust from there.
 
Everything seems ok from what you mentioned other than temp seems a little high. Coco/Perlite media will dry back faster than regular soil potting mix unless your mix also has some peat but from what I'm seeing in the picture it looks like pure coco and perlite.

Especially with coco/perlite use the light pot method to know when to water. Here is what I would do. Turn down or raise your light and back off the amount of light intensity you are giving the plant. If you don't have a light meter app on your phone I suggest you download one. They're free. I have an android phone so I use Tent Buddy but there are ones for Iphone also. Stick your finger in the media all the way down to your second knuckle. If the soil feels dry, remove your finger and pick up the pot. The pot should feel fairly light. Remember this feeling. This will be your signal to water.
Water the entire media making sure all the media in the pot is wet and not just around the root ball. When the root ball sucks up the water in its immediate vicinity it will grow roots to find new water. If the media around the root ball is wet it will shoot tertiary roots to get that water. Next time try and center the plant in the pot for even root distribution throughout the media.

Your plants are probably stunted so it'll take a few days for them to recover or it may recover immediately. Depends on the condition of the plant.

Coco doesn't hold onto water as well as soil due to its makeup. You stated the soil is organic. Is it amended with dry nutrients and you just use water? Coco is notorious for being magnesium deficient. Are you feeding your plants anything other than water?
 
I'm gonna go with some of the others here and say they look very thirsty. As a plant grows so does its need for water. Once a week seems kinda stingy. If you have proper drainage it's hard to overwater.
