I have a Zkittlez auto in tupur mix.
It’s 9 weeks from sprout and starting to flower.
Tent is always 55-65% RH and 70-75°F.
Feeding it 2-3 times a day 6-7/gal GO BioThrive Bloom (2-4-4) and 5ml/gal CalMag (2-0-0) in RO water, Ph to 5.8-6.0 and EC 0.8-0.9, 550-650ppm.
Measured the runoff at ph 6.1-6.2, EC 850-950, 550-650ppm.
Today for the first feeding I’ve upped the BioBloom to 10ml/gal and Calmag to 6ml/gal at 6.85ph, 1.07ec and 740ppm. Runoff was 5.98ph, 1.01ec and 690ppm.
I’ve had a cal deficiency with it so that will likely be in the photos as well. Now I’m seeing dark, almost black blotches on fan leaves. This is my 2nd time so I’m new but with looking at charts the only thing I could figure is a phosphorus deficiency maybe?
Any help or advice very much appreciated!!
