Afterwards, ive experienced droopy in the past due to root bound but nothing like this as well as they do look a little happier this evening it was time to transplant anyways i was going to do it this morning and did it last night in hopes to help them.I agree with the others, looks like overwatering. I'm a little confused on your verbiage about transplanting tho.
Did you transplant from solo cups to the pot before or after you noticed them looking sad? I'm sorry if It went over my head lol. I'm at work on break and busy with my head all over the place.
40% humidity canopy sits rpugly 35 cel i usually go off weightz and looks of tops was now 3 days since watering last they took 750-1000ml each to gove run off i only water ever untill i see run off not my first run with these plants but first ive experienced this for so long they seem to be back up and very happy again.I'm not a soil grower but I,d go by the weight of pot, watch for the soil starting to shrink/crack a little (maybe to extreme) the amount of water used is dictated by your environment there's no set amount or frequency.
How much water did you give it how long ago?
What are your temps at the canopy?
