Hi guys once again need some peace of mind on this problem I have just found. Didn’t see any problems yesterday however today I have gone to feed and found these little markings and browning spots; Checked every plant for pollen sacks and all females I am almost certain.

Hoping so! I am going through every rabbit hole in my head. My PH does vary but I never let it go over 7.0 or under 5.8. I try to get it at 6.2/6.3 and do most times! What about the thricomes going orange though? They’re only 3 weeks and 3 days into flower
