Still fighting whatever it is that's causing my leaf problems. I hadn't flushed since before flowering started and I'm kinda thinking it's a nutrient burn/lockout issue, I've been feeding them max strength with bloom booster almost since flowering started. I flushed with 2 gallons of water and then for the next feeding only used half strength on the nutes without adding bloom booster. I'll be alternating with feeds/flushes now, so we'll see how it goes.
