sunshine pro mix 4, soiless medium. theres no nutes in it, so you control them. i think a big contributor to my "no problem" grow has been my nutes, botanicare pro, grow and bloom nutes. botanicare, i now find, is a beginner nute. not hot at all, but like i said, i havent seen any burn or deficientcies in my grow, as of yet. the young veg gets like 1 tblsp/gal, of botanicare grow, it goes up to 3 tbslp/gal of botanicare pro bloom in late bloom. just follow the directions on the back. i use a veg additive, superthrive, in veg. a couple tsp/gal to each feeding. i use a bloom additive, general hydroponics, kool bloom, for fatter nugs.
im switching over to general hydroponics flouranova this round. its a way hotter nute, but im gonna step it up, (1/4 strenght up to full). its cheaper, and i hear, a top notch nute. i only flush once in veg, because my veg runs 4 wks, at the end of veg. also i flush after day 30 bloom, then the last week of bloom with molasses. i dont use molasses till the end flushes. so far so good. i dont know if this is the right way, but i do know that i have no problems yet. i only water when they need it, i dont ever over or under water. ive seen the leaves wilt a couple of times, but i really feel like i got the watering down, hope this helps! im not trying to be cocky, i really just want to tell people what i did, maybe it helps. i run 5 different strains, all of them i feed the same, maybe i just got lucky.
if i could give all of you guys clones i would, i always have like 20 extra, healthy, no pm, no sm. im just here to help.
