Hi guys so I’ve noticed my 12 day old ladies haven’t grown at all in a week... im 90% sure its due to overwatering. 2m X 3m tent, I’m growing 20 plants, 4 strains in 5 gallon fabric pots 75/25 coco perlite hand mixed. All plants are exhibiting the same stunted growth. 2 are actually drooping. whenever the top of the coco got dry (about twice a day) i was watering about 250ml evenly around each pot with a watering can. Since I started thinking it was overwatering I haven’t watered for 48 hours and although the top inch or so is bone dry, probably due to my cmh lights producing a lot of heat, its still got a lot of moisture still in the rest of the coco. Temps are 23-24 Celsius (73.5-75 Fahrenheit) and about 40% rh. I’m really worried about the stunted growth affecting my yield as they are autoflowers. I’ve attached a few pictures, can someone please try and help me try to get them growing again? Thank you so much.

It's extremely easy to overwater little seedlings in 5 gallon pots. 250 ml is way too much. Seedlings send a tap root straight down very quickly-that root has been sitting in water all this time. You really only need to moisten the area immediately around the seedling with like 10 ml or so. You mention CMH lights? How many watts and what distance is it from the seedlings? Those are powerful lights to start plants under from day 1. You might have a couple of things going on here.

Fans would help, and maybe a large blanket underneath long enough to soak up some moisture (but not long enough to mildew!).

Yes, i have 4 x 630w CMH DE lights on 80% (which is the lowest the ballast goes) , Only 3 of them are on, which 6 plants roughly below each one to save on electricity. and they are about 40-45” above the plants, i moved them up about 4-5 days ago, before they were 32” above the pots. Thanks a lot for your reply. I’m really worried about the yeild now, i was aiming for 100grms/plant but now I’m thinking i wont even get a quarter of that.

I have a floor standing fan on, set up at the lowest it can go, but even at its lowest it still blows the air about a foot above the actual pots. Still got it on anyway hoping its helping. Thanks For your suggestion.
