So looking throughout my canopy I’ve seen some older big fan leaves starting too have some brown spots any idea what it could be ? Check the rest of the leaves and their all okay
Sorry dude I can't see anything wrong on them pics, you may have a little nute burn on some tips but nothing I could see that would make me worry. You should be lowering your nutes with N in and increasing your nutes with P and K in around now. Good luck.
