I use the nutes that are in the Miracle grow moisture control soil. I use epsom salts, molasses, and shultz plant food if I need to and I use shultz expert bloom, when I'm flowering. That's it. I get them all from Ace hardware. nothing fancy. I use neem oil if I think I may have a mite problem. Or actually to keep from getting a mite problem. I use pyrethrum if I do get a mite problem. If I get soil gnats that are actually in the soil I use a potato slice and they come to it and then I get it out.and do it again. Like I said nothing fancy ever. All of these things are found at ACE and are fairly cheap.
