They seem good. I’ve went light on the nutes to be safe. New to hydro. Not sure what light height should be. I started at 17 inches went up to 19 inches now. The branches seem really close together but she sure is pretty.
Yeah man, unless your on a hard budget, I’d recommend a little air pump and stone.. even one in there should help. I know kratky is a viable method but to me it’s worth the movement and oxygenation of water to have a pump and stones. Good luck!
Edit- I just say it does appear you have a pump, I guess you just meant a circulating pump.. anyhow looks good!
