I like bloom boosters, but I grow in coco or other hydro, never really messed with dirt more than a few runs. I don't feed the full recommended dose, but I never do that with any fertilizers.
To call that's guys flowers and plants mids is just rediculous. Especially when you couldn't provide any pictures to the contrary.
I'm not gonna argue about flushing, but I do it and I like to fade my plants out just like his. I've done both over the years and prefer well flushed buds. Just cause science can't figure out the difference yet doesn't mean there isn't one.
As far a cure being 50% of harvesting quality that's bull shit too. Yes a bad drying and curing process can ruin good bud, but if you can't grow well curing it for a year not gonna make it better.
