Had some issues in weeks 7-9. Wanted to flower sooner, but nutrient deficiencies likely caused by ph too high caused some issues. Did not want to switch to flower on unhealthy plants. Now back on track, though one plant did not rebound. The sick plant has been removed and moving to flower as of next week (week 11).
Deficiencies caused yellowing leaves, brown spotted leaves and stunted growth. After ph balancing the water and adding CalMag to other nutes, most plants rebounded nicely. I did some defoliation after the problems were corrected.
