As for as people not adjusting pH for their water, that is because they have a low pH coming out of their fuacet more and likely. I usually have to add pH up after adding nutes. I had problems using botanicare with hempy, but switch to GH flora and everything looks great now. I just mix two gallons of RO water add half strength GH 3parts, then pH up. Let bubble for at least an hour or until ready to feed.Gird, I can't speak to time release. I use the GH Maxi series mixing it just as it states on the bag and pH it. That is all I use until the flush, no plain water, nothing. How can you dump that much nute mix and not have a problem? I don't really know but, I don't. There are some who say that you don't even have to pH for hempy, I can't speak to that either, as I have never tried it. Good luck with whatever you decide on.
