I always used Florel around 3rd week in veg. Florel is nothing but ethephon which is converted into ethylene as the stomata absorb it. (Foliar spray) Usually worked fine w/huge percentage of all that I've grown (around 95%)
But due to circumstances I've had to change my growing area. I have had to use a cabinet as a flowering chamber about 3 1/2 ft tall w/HPS light. All of my plants start showing pistils 1-weeks flower---but they seem to be shriveling then developing lotsa nanners!
I thought it was the heat--or maybe my Florel is old
Is it possible for the plant to hermie into a predominantly male entity AFTER it has shown pistil preflowers and development? Is it the heat/humidity?
Peace love and hairgrease
