I used Fox Farm nutes religously for my first few grows, and it's not snake oil at all. It's very good synthetic nutes that stack on big heavy buds dripping with crystal. I just always changed the schedule on the trio. I use open seseme first 2 weeks beastie 2nd 2 weeks, and cha ching weeks 5 and 6, and then just watch the plants to the end. If they look like they need a boost, you can feed em' a little more cha ching, or like I used to do and give em' a little mollases or something like that to get em' through to the end. If you continue to feed like they say to, you have to flush real good then, but all in al, it's good stuff, and it's easy to use. I do all 100%organic now, but if and when I feed any synthetics, FF is what I use.
