“There's an old saying in Tennessee — I know it's in Texas, probably in Tennessee — that says, fool me once, shame on — shame on you. Fool me — you can't get fooled again.” George W Bush
Personally used only HPS for Veg and Flower, said that HPS creates shorter node distance so bushier plants, wont really affect them badly at all, Flowering Under MH will HInder bud growth since the plant is not recieving the right "color" of light for Flower Production,
LST for the win, No wait for tops to recover, no stress from cutting, can achieve the same if not more tops as FIM and TOPPING,
Downfall: It can get kinda bushy so defoilation is also good to practice,
