I am on week 6 of flower. What else can I do to increase flower weight and bulking up? Also, do you recommend any flower hardener like Avalanche Flower Hardener? Thank you
Imo Athos is kind of right... If you don't get optimum light intensity and temperatures then the "extras" won't help a whole hell of a lot. Their is enough research to support that the additional nutrients of course fucking help but it has to be grown at optimal levels. Lots of farms and commercial outfits use the extras for a reason. If all they needed was the base 3 formula that's all they would use as they spend thousands of dollars every year on nutrients.
Your yield depends on the amount of light and your skills as a grower (transplanting, watering, training), not what nutes you give the plant. Don't waste your money on anything other than basic nutes.
