I didn't say anything about not checking pH. I use vegamatrix right now, and it pH'es itself...if you use the chart they provide. However, their chart will burn all but the heaviest feeding breeds, So I make my own schedule and have to check or it'll be all over hell. I also use silica once a week till second week of flower, which requires a lot of down to equalize. So I'm a pH checker. As far as the additives go, I use the "Big and Sticky" from Vega. at half strength, from week three through seven. honestly not sure it makes a huge difference, don't think I'll use it again when this quart runs out. The best thing I've found so far is UV light. If the additives work for you, rock em. I just am finding that less is more in a lot of things.
