giving defoliation during flower a try

I know for a fact that when you let the PH swing down to 5.2 or so your Potassium and zinc uptake is better but nitro and mag can get locked out. This is a good level to periodically hit during mid to late flowering. Also an upswing to say 6 to 6.2 will get you a better uptake of sulphur. I'm not talking all the time , just for like 4 days or so at a time from 5.8. Swing both ways, like Chuck . Try it before you knock it.

No ur wrong again. The ph in ur medium changes as salts accumulate and things like lime breaks down which is found in almost all mediums or oyster shell if u runnin coco. So u usually need to raise ph of nutrient solution during flowering. Bcuz that what causes the yellowing and leaf drop ppl see by time they add pk boosters bcuz the rhizosphere probably off. So swinging ur ph stabilizes nutrient uptake by giving it a better range to balance ur mediums ph accordingly which usually becomes acid as the grow time increases. Most soilless mediums are acidic by nature which is why we add lime and she'll to buffer it back up. But those only last for so long so stfu u dumb as fuck.

You adjust your PH by adding lime to a soilless medium? What the fuck? If you can speak/type fucking English in a understandable manner, it would be helpful. Please explain further, as I am stoned and confused.

Yes lime buffers ph in soilles mediums like promix. It's a natural buffer what's so confusing? You didn't know that was the purpose of lime? Huh..
