GrowerOGanswered grow question a day ago Hello mate, you might have different couses, starting with genetic ending with mistakes from you. I see from your diary that you have 23°C with 75% RH, you have the correct RH but for an highter temperature like 25-27°Cto give the right VPD for this stage. I think also you have you led dim at 100% now, even if you put it at 70cm of distance the intensity of the light is too high for this stage, try the 50% at the same hight. You give they a solution with pH 7 that is too high, try to keep it around the 6.2. Also until the first/second week of vegetation a prefertilized soil is enough so don't feed they if not with only water.
Now you sould let rest your little ladies until you'll see normal leaves come out then you can think to train and to feed them.
Good luck and happy journey!
