I'll admit, most of my growing knowledge comes from Cannastats which leads me to my question.
I've always accepted as fact Mel Franks nute requirement of 100N-100P-200K-60Mg, although I like and follow pH Imbalances guidelines in the MJ Handbook, so basically I'm doing Lucas with GH Flora. Thing is, when I mix my solution to their guidelines my PPM are much less then what it says in what I read. I know it's not the right thing to do but I use tap (3 stage filtered) water for my grows and it has a TDS of 325 from the tap. When I do the pH Imbalance dosing for flowering (0G-3M-22B ml/g )* plus 5 ml/g Liquid KaBloom I get to an N-P-K of N40-P186-K309 but my TDS is only 1100 TOTAL even with the added 325 TDS of my water. If I up the nutrient ratio to meet the extrapolated PPM, I'm going to end up bumping my N-P-K figures even higher, which I'm concerned about due to possible nutrient lockout. So is my math correct? I'm using this for my calculations PPM Calculator If my figures are correct which is the best way to go? Go with a lower TDS and supposedly correct profile or higher nutrient concentration, throwing the Mel Frank guide out the window?
