Top Booster, Bud XL and Shooting Powder should be used by more experienced gardeners in my opinion... and they can take time to dial in to each strain for the right doses... if not used correctly they will stress your plant as much as they help... I like Canna or HG's entire line for flowering, except for those stimulators because even a semi-experienced grower like myself can get it wrong with those nutes sometimes... but bloombastic serves as a really potent bloom stimulator and its easy to use and very forgiving... Myself and many i know have nixxed those other complicated stimulants and replaced with Bloombastic. We get even maturation and a great balance of quality to quantity. I start low doses in week 3 and work it up to heavy doses in weeks 5+. I have some pics below my 2000watts hydro over drip tables, these are in perpetual stages, sorry the pics are blurry, i will post more showing clearer closeups tomorrow, but those buds on the right are in week 5 and they are hard as rocks already, the other table is at day 8 of flowering, they look flawless...
