I have 3 plants, all humboldt dream but one is giving me odd deficiency or disease that I cannot pinpoint. Maybe those more experienced can explain what is happening and how I can fix it before the crop is ruined.
planted in 3gal pots, 70/30 mix of coco/perlite, day 44F, using AN sensi bloom for coco & AN big bud for coco. Run off is 5.7ph and 1250ppm (my water is 300ppm).
The issue started a few weeks ago with one cola and now effects maybe four of them on the same plant. Started with spotty sugar leaves that progressed.
Light stress? Could be lockout. I had similar on my auto grow. Shouldn't soil runoff be in the mid 6s? Calcium doesn't uptake until 6.2 from my understanding.
