RIU - a raccoon invaded the grow. Doesn't look like it was eating anything but it did trample over everything and tried to climb the biggest girl. Had to relocate them which disrupted the photo period. Now back in their place I am noticing all the tops appear to be dying off. They are fading in color and/or turning black. I've never seen this before. This mother blackberry has been in VEG for about 6-8 weeks but I am seeing the same on younger girls of different strains. Any advice appreciated.
