I don’t understand the vpd cart at all it did have a over watering problem but then I reported it and now it’s growing so maybe root bound cause when I lift the cup I can see them for sure & what do you mean 3 layers could you circle and show me ) and would it be soon to fim or top ??Looks rootbound and overwatered or maybe vpd issues. I'd repot and pull off "everything" on the bottom three layers.
Look up a vpd chart and see if your temp/humidity is right. Could also be light issues, it looks awfully blue.
it’s already 27 inch away
What should I do to improve do I prune like the dude was talking aboutI have no experience wih a lamp like yours but my 315 cmh needs to be 40” away from plants that size.
I backed it away until the leaves looked flat and happy. The recomended hanging height was 20” but that is good for peak flowering mature plants when i tried.
