Came back from a short vacation and found my 3 young blackberry plants suffering from what looks like nitrogen toxicity. Plants are in FFOF , transplanted to current pots about 2 weeks ago ,they seemed to be adapting well.
600 watt mh light 20" above plants. I flushed with plain phd water today. Pic is of worst of 3. Black in veins of some leaves also. Any suggestions?
