Feeding question in week 5 (stumped)

Think this is a balance issue or pH. Try raising pH a tad, unless specific instructions from your nutrient brand says otherwise. 6.3-6.5. I'd try that before playing with the formula... it's a safe ppm overall, but ppm of any individual element could be out of whack even in that context. i think that's going to take away any potential deficiencies on its on. otherwise, continue to look into it and calculate ppm's from your labels per nutrient. compare to any formula you can find - lucas, jack's whatever.. get some ballpark ideas of ceilings. Might just need a bump to nutes too... whatever the data dictates. unless you have extremely high chlorine levels, you can save that effort if you want. check local water report.. likely no big deal.
