I agree its a myth

as to the leaf removal....think of those fan leaves as bud engines...just tuck them out of the way to allow lite next time


no more nutes, actually Id give her a final flush now....the leaves are very dark green for this stage which means you have more than enough nutes there in the plant alone to finish it out & your droop may infact be nitrogen toxicity, given the dark, dark green leaves.
on the last gallon of flush add 2 teaspoons of molasses as a carbo boost and the sugars aid in the breakdown of chloryphyll, for a better final taste
