the Fox Farm feeding schedule makes it all nice and easy ... I use FF exclusively, in my hydro, too, great stuff :thumbsup: ... I use their Big Bloom throughout the grow, it's really not much of a fertilizer, as it is live organisms, that break down the nutrients, so the plant can absorb them ... I start the Tiger Bloom the week before switching to a flowering cycle, dropping the FF Grow Big ... Fox Farm is good for outdoors, too, but pricey, if you have a large garden ... my 'outdoor commercial-growing' buddy grows the biggest, healthiest plants I've ever seen in my life, (and, I'm an old fart), and, he uses nothing but Miracle-Grow, bought at the hardware store ... not a damaged leaf to be found, simply amazing plants ... used at half-strength, once per week, plain water the rest of the week ... amazing, best word for it :thumbsup:
