Okay, so I foliar fed them yesterday with manesium and seaweed concentrate for P and K. I took a pH reading with an electronic soil tester. This thing can't be right, it showed a pH of 5.2. It has to be an excessof nutes causing a lockup. I'm 2 weeks into flowering and at this point thinking it may be too late in the game to mess with pH. I may continue foliar feeding to keep them going. Anyone know of any simple steps t at least boost the pH a little? Should I just stick with what I'm doing and hope for the best? Also, I found a source of manganese which I was looking for in "Schultz Plant Food Plus. Any feedback appreciated.
