I gotta agree there also. The only time i tried molasses it actually made things worse i think. Simple sucrose CAN be absorbed and its in some horticultural products. But molasses isnt one.
Stuff like florakleen is actually an isotonic sucrose solution i believe, it gets taken up and displaces the nutriemts in the vascular system.
And i agree that grow ratio is all thats needed and is likely the least stressful feeding routine.
But, I do believe used conservatively at the right times, P can be used to our advantage. Just look at Burnzy's room.
