im in week 5 of flowering, and my leaves are turning yellow. I don't know what the problem is but I know its not good. it started off with yellow spots on the edge of the leaves, then turning the leaves fully yellow/brown, and now falling off. I gave them some cal-mag about 2 days ago and nothing has improved. I have this feeling I messed up and made the soil to acidic. I don't have a ph tester for the soil so I have no clue what the ph is. if anyone has some suggestions it would be great. im pretty sure the soil is to acidic tho. I was looking into solutions for acidic soil but im seeing that I shouldn't do anything and let them be because they are to far into flowering.
