Is this pH related?Hello, mates! Anyone knows what this could be? Searching I found that it could be pH related. I use pH controller from ferts (pH perfect from advanced nutrients) since the beginning, so I think it's odd that it could be a pH issue. p.s. 3.5 weeks of flowering Thanks 🙏 🙏

Heat stress? Light stress? Nute burn?Hi y’all Since my girl started to flower the top leaves near bud sites have this weird cupping downwards look. I doubt it might be a nute burn since I already gave her a good flush. I think the heat might be the main issue (86-87degrees during day). What do u think? Day38autoflwr
