Yellowing and spots

How do I bring pH down?! Can I use ghp up/down in soil? Feel like that killed my plants last round, I am having VERY bad luck the last two grows. I've never had this kinda stuff happen with bag seeds, but now that I go with a better setup and actually purchase seeds this is as far as I've got. And it was after stopping using ghp down.

He wasn't suggesting to bring the pH down at all... your plants just look deficient and in soil, a too acidic pH could cause problems with the Ca/Mg uptake. But it could as well be that your soil is leeched empty and you need to feed (always feed @ pH 6.5 in soil)

I'd apply a strong foliar feed with Epsom Salt, chelated Fe & Urea. And in the interim take a slurry probe to check EC & pH of your soil and then go from there. No clue how high you did charge the EC but just add 30% more of a full veg formulae fertilizer, or some specialized "green"-supports like CMX.

Or you find your pH is out of whack - then you just need to counterfeed and wait for the plant to sort this out.

A few humic acids may also help in nutrient intake.

Would I be stupid to think that I might have over-fertilized and I'm getting a nutrient lock out? I use black Gold soil btw.
