Is it Just for hydro?Does pH and ppm's go hand in hand?I have some plants that are yellowing earlier than I would like them to.I grow in soil(Happy Frog)in 1.5 gallon pots,GH flora 3 part nutes,mixed to labels specs,with cal-mag during flower.Currently running 3 different strains and one seems to be yellowing more than the others.Would that make the one strain a heavier feeder?How would I increase the nutes over the labels instructions?Adding more nutes would up the ppms I assume.What is a good level of ppms for feeding the girls?I don't want to just add more grow nutes and over do it.My other girls seem to be just at the limit with just a little burn on the tips of leaves following the label,but the ones I'm talking about eat that up and start yellowing early.Since there isn't more mixing ratios on the label I figured the only way to mix stronger is to measure the ppms of my nute solution.So I need a good baseline or table of recommended ppms for the different stages.Any ideas?
