So this is my second year of growing. I went from 1 plant to 12. I have 2 White Rhino, 2 Northern Lights, 2 Ice, 5 BlueBerry and 1 Bubblegum. I am getting a little worried (depending on who I talk to about the yellowing and purpling of the leaves. I am about 3 weeks into the flowering with about 3 or 4 left on the BB. Please comment on your thoughts about the yellowing. I have been following Foxfarms feeding schedule, but now I am flushing because I am not sure if I should be worried about the coloring of the leaves. Maybe I need more nutrients? Less?
