if you guys can show me scientific evidence of flushing, then I'll believe it. Sorry, just because jorge cervantes says it doesn't make it fact. just because its chemical fertilizers doesn't mean the plant will taste like chemicals.
the plants absorb what they need and convert it into energy. what other fruiting plants in nature are flushed?
if an organic grower didn't flush, would their crop taste like bat guano? if I plant jolly ranchers in my soil, will it give my harvest a fruitier taste?
as for light leaks: if it's a POWERFUL light leak, then yes maybe it can cause a hermie, if the light is powerful enough for the plant to snap out of its dark cycle. I have left my grow tent open many times with my room light on, and I have yet to see a hermie over 4 harvests.
