Hey razzor I've used nf full line old and new. It definatly works. If you're mixing in a res the additives seem to get something growing in there and I was using waterfall plus pump in the bottom moving things around and oxyplus. If you go to their website and click on a product you can find a MSDS PDF. It gives a clearer picture of what's in the bottle and you'll find more than one product shares the same ingredients in one way or another. I think from memory you could get away with cargo boost and crystalic for the whole grow. Crystalic has the fulvic acid, kelp and molasses and cargo boost for the citosan. From my experience I could never go over about 1.0 EC without experiencing dark leaves(N-tox?) mild claw, leaf tips curling up, soft stems. My temps were good but fresh air intake could have been better so might have been a factor. If you wanna try the additives, start out on the lower side of things I reckon. Pretty sure in the end I was down to boost and crystalic in half doses.
