    Just the top of stem is ready, why and why just top half?

    I searched here and found info on red stem but I only have a red on the top edge only. They just received their first full dose of Bloom nutrients @ 975 ppm & 5.8 ph. The temperatures outdoors have been ranging from 80 highs to 65 days, to 69 to 50 degrees at night. Hope the picture...
