2 of my girls is showing an issue and im unsure as to whats doing it

Perhaps early transplant stress or overwatering. The curl and pale color suggest roots aren’t thriving yet. Let the top inch dry out well between waterings and ease off on intensity if lights are close.

Hey there I don’t really see signs of ph issue when ever you can water enough there will be run off you can check the run off water ph but till then I’d just focus on the rh also maybe back down the light just a little bit to let the plant recover. The plant is going thru the stage where it hardens off. Sometimes if you let the plant recover for a day and leave the light super low like 50umols for a whole day then go back to that same light u had b4 the plant will bounce back also you maybe need to start watering a bit more so those roots will get all thru that soil ..,..
