What's the deal with fox farm? Read a lot of good on this site and others. Does it leave salt deposits? I'm not really trying to go all organic, just trying to produce a good product. Even if don't use on my mj plants I can use it on my veg garden, got about 18 tomatoe plant and some other shit.
Everyone's got an opinion, so here's another one if you want simple but good results and don't care if it's not organic. Use the sunshine #4 with some dynagro 7-9-5 and some protekt (silica) and their mag-pro (only if using r.o. water will you need this one and probably only in flower). They have a bloom formula you can start slowly replacing the grow out with a couple after weeks of 12/12. The ratios on their bottles are fine to follow, but use about 1/3 - 1/2 of what they say as it's way too high of ppms as most nutes schedules seem to be. Their stuff is cheap, easy to maintain and will give good results imo. You can just "water" the promix with your nutes in a feed, feed, water regimen as needed when the pots dry out. Homebrewer has some threads here showing some very nice results with this method in 3 gallon buckets if you want to see what sort of results you can achieve if you use this simple way to grow- his pics look better than most on this site and the smoke reports are always very good. You'll have to learn to read your plants, but this is so easy I think just about anyone can get good results with minimal fuss or money spent. If you start to see yellowing on the leaves, just add more grow instead of bloom- keep em green till the end without overloading ppm's and there's no need to flush either. This is how I keep my mothers (except for the flowering part of course) and I haven't found a way I like any better so far.
Edit: you may have to flush excess salts once every few weeks if you notice any salt buildup in the soil or slowed growth, but that's the only kind of flushing I do as opposed to starving them unnaturally at the end of their lives when they are trying to pack on weight. After the first grow you'll probably have it down real good for any future grows. And it seems you have somewhat of a green thumb even with what you're using right now so you'll probably do just fine.
Although chemical nutrients are chemically identical to the byproducts microbes in soil turn organic nutirents into (in organics the microbes are needed for conversion, whereas the chemicals are already in the form directly absorbable by plants), I am curious to try a head to head with organic vs chemical. One thing is for sure, chemicals are easier and offer more control- and if you have any nasties you can just add some chlorine to the water to keep it sterile (6 drops bleach per gallon is fine). I definitely prefer pure organics in my veggie garden so I am not against them by any means, but I am still learning the art of organics as I've done hydro so long and it's just a different world with organics. There is always a possibility the chemical nutes do not contain things offerred by mother nature that we just have not been able to understand or see in a lab, so that's always in the back of my mind.
