Question about a product

Hey all, looking for some input from you guys and girls
while i was reading on here, i saw a lot of people talking about bloom boosters and such. currently im using the holland industry, 3 step program by floratonics. i went to the hydro shop for a new bulb and fan speed controller. while i was waiting for him to get these things, i looked at a product called "weight bud pk 14-15" and i believe its from the same company. i cant seem to find any info on this product and was hoping someone here could let me know if it was a waste of money and, if not, how well this stuff works.
im not expecting miracles from this, but i would be happy with a bit more density in the final product
im not sure ill notice a big difference this run(from the booster) because i jut switched from a 400w hps to 600w hps on day 29 of flower(today).
the product says i can start as early as week 4, which is perfect timing lol.

Never heard of it and never heard of those nutes. For weight and desity though I can highly reccomen Gravity from Humboldts Own or Sweet from Botanicare

ive seen the 3 step nute system run by someone else here a while back, but ive yet to find info on this weight bud. im happy with the nutes this far but ive got nothing to compare them to since these are the only nutes ive ever used lol.
anyways, thanks for the heads up! ill see if the hydro shop has those products when these ones are done with

I usually run Fox Farm 3 bottle nutes Grow Big Tiger Bloom and Big Bloom then I add the gravity, cha ching, beastie bloomz, silica, snow storm and Bud Candy

jeez, quite the lineup youve got! lol
on these forums all i hear is AN and FF.. maybe i should have looked into those a little more. the stuff i have now is great so far, but again, ive got nothing to compare it to. hopefully its not been a waste but the girls seem happy so who knows.. i guess ill have to try another set of nutes for my next run and see how much better or worse it is
