You got some tip curl which is often indicative of overfeeding but you say you're feeding RO water only? Also I have a suspicion those plants are being kept wet & not drying out between feedings? I'm not sure if that would do that because I've never seen that, but that's what I see so far without more info
Okay so eliminate that, so talk about pH and are you feeding any nutrients at all?I've been letting the pots get bone dry before feeding
Okay so you got to stop letting it soak up its runoff to start, not positive but I suspect that's why it's drooping like that and it's going to cause you problems going forward in my opinionI've been feeding it straight RO water without checking PH (I was hoping FFOF would buffer PH for me). I wasn't planning on doing any additional nutrients. Once it grew a little bit, I was going to transplant it into a 5 gallon filled with 1/3 super soil & only feed it water at that point.
I was letting it sit in it's run off since I add no nutes, but it usually soaks it up by the next day.
