They look like they're hungry for light and nutes imo.
@Olderfart does great things in coco, he may be able to help.
@Les @HLG is our on-site HLG rep, idk if you've gotten in touch with him here. As far as the lights go, I like to keep mine as high as I can get it and just vary the intensity via dimmer as needed. The scorpion is 34lbs and trying to move it up and down with plants in there isn't going to happen, and since I grow in 10 and 20gal pots moving them isn't either lol. I usually run perpetual so I have newborns and girls ready to come down all under the same light at the same time.
