Holy bad advice batman!
1) Do not ever put a fan directly on your plants. That increases transpiration causing leaf cupping and curling. Cannabis leaves should never do more than a gentle dance. Certainly never a fan pointing directly at them.
2) Flushing is absolutely voodoo quackery. There is absolutely unequivocally zero evidence that flushing affects flower flavor or burn quality. You cannot just "rinse" away nutrients that are stored in plant tissue. If you were awake at all in science class for the last 4 years of your high school education you would know that makes no sense at all whatsoever. Flushing is a practice invented by the predatory cannabis fertilizer industry in an effort to sap more money from your wallet and into theirs. There is no foundation in science or agriculture for such a practice and does nothing but make you sound foolish to anyone that knows better.
Learn about how plants absorb and store nutrients and you'll quickly stop spreading misinformation. So-called "flushing" is a practice most often utilized by low information new growers that get all of their growing knowledge from the company that's selling them their fertilizer. The very same company that sold them 10 different bottles of fertilizer to make the plant grow right. The real secret is it's all bullshit. If you don't over fertilizer your plant throughout the grow cycle using the fertilizer company's 10 different bottles that you don't need, then you won't have to be concerned about "flushing" anything out of your plant. Good tasting and proper burning flowers happens with a proper and balanced fertilizer regimen throughout the flower cycle and decreasing fertilizer strength towards the end as the plant's needs diminish. You don't "flush" anything.
3) You most likely are experiencing a toxicity issue of some kind, because you are over fertilizing your plants. Maxi bloom is a complete fertilizer with micro nutrients. Why are you adding flora micro also? By adding flora micro in addition to maxi bloom you are over fertilizing your plants creating toxicity with 1 or more elements. The evidence is allover your leaves. By over fertilizing throughout the grow no amount of "flushing" will make those flowers taste good. It appears to be calcium toxicity. Maxi bloom, magic cal, and flora micro all have calcium. You more than likely would have done great with just maxi bloom. It's what I use and is a complete fertilizer. I have rarely ever had to supplement with calcium or magnesium.
4) Stop defoliating. Stripping the bottom leaves and branches that have no chance of light access makes sense in an effort to create a nice canopy, but tearing your leaves off at the canopy level is crazy. You need those leaves to make energy to make flowers. Stop plucking them off.
5) Start getting better advice, and I'm still genuinely baffled as to why you would add flora micro to maxi bloom. Just baffled...
