2 weeks into flower and a lot of lower leaves are falling off with black patches appearing. Some leaves that look perfectly healthy seem to fall as well. Honestly any information would be great.
Ah nice one bud......been using the canna range but not sure. Seem to always get some sort of issue with. I did rush in and put blackstrap molasses in the reservoir and for some reason knock my ph real low. Do you use advanced nutrients full range?
