yeah It looks like they are trying to come back but very slowly I mean if I killed them they would be looking at lot worst by now right? The Hydroton is wet on the bottom it doesn’t make it all the way up unless I’m doin something wrong?Compare the pics you sent from the start of this post to now...notice your leave petioles are more up than down...they're trying to come back; be patient. I have no experience growing the way you are, but should your hydroton look so dry or is it wet underneath? Just curious.
