Im having a good bit of leaves at the bottom turn yellow and get dry. the smallest girl she has some of her leaves in the middle start to look brown on the edges. I gave them a 2.2ec feeding of FF big bloom (fertalizer) and tiger bloom @ 7ph i think. I gave them worm casting tea that had some FF fertalizer, AN voodoo juice and wormcastings. They looked amazing the next days but why am i getting yellowing still?
