thats weird i have 6 growing that are 26 inches tall..vegged for two months..week 6 of flowering..
also watched a video of outdoor GG that was no more than 3 feet tall..pretty much all of them...
most rare pheno you just happen to get?? ;/
if you already have pk 13/14 then i say use it. but if you dont have it. id say its not worth it personally. ive never used vitalink products i just looked it up though..personally i would use one or the other..
and to think of it.. i remember looking at the ingredients in the bloom bastic bottle..if i remember correctly its the same shit as purple maxx... if you have ever used it..
i think bloombastic is over priced and so is boost..
save the money and just use gh bloom youll be just as happy..and your wallet will stay heavier...
also i took some advise from a grower on here and went without the pk13/14 on a few of my plants..lol they look the same..so probably wont be...
