35 days and needing a new home in a bigger "tent"
They seem to be doing really well, getting fuller over the last 5 days. I have noticed some tip curl and tip browning in the fan leaves as of late. Too much N? Temps 68-77 (humidity 50-65% ) any advice?
Without more information it can be difficult to tell why you have leaf tip scorching and along the serrated edges. Often times it's related to over-feeding, but allowing your media to dry down severely can cause leaf tip scorching too.
A picture top down of your plants would be helpful in helping to diagnose the issue. Have you fed them any lately?
