a pk booster in week 5 of flower is a good supp. to use. there's a lot of others too.
like what pk boaster should i use?
right now i am growing AUTOS , is it worth to invest some cash in some nute like "Humboldt g10?
right now the only nutes i have is "bud blood" (which someone told me to use only the 1st week of flowering) and "snow storm"
i also have a nute juice that is to be used for cactus plants but its high in "phosphate" 7% and "soluble potash"7%
should i just feed the autos the cactus plus "plant food"?
cause if i order g10 from Humboldt its gonna take a while to ship and by the time it arrives it will be too late to feed!
