Hi mate, the spots suggest more of a calcium deficiency to mem but like you say your ppm is on the lower side. If it were me I'd up the feed and add cal mag (more if you're already adding.) But be careful as cal mag contains N so make sure to limit the N in your other products by looking at the NPK values.

Calmag every watering?Should I be adding calmag+ to every watering? I've been using 50/50 pur+ tap water and distilled water. Ppm is 245 at 50/50 and pur+ filters chlorine. I've also added 1tbsp per gallon of unsulphured molasses and that adds 68ppm. Day 40 right now.

Leaf tips browned. What nutrient problem is this?Leaf tips browned. And some signs of burn/discoloration at the leaf side edges. Do you think it's general nutrients overdose? I didn't increase my PPM for the last two weeks, so I don't think it is a problem... Or Potassium deficit? Or any other secondary nutrient deficit?

Nitrogen toxicity? Deficiency? Something else? Stumped!I don't get it. Is this N toxicity? Serrated upturned edges, clawing, slow growth. But how? FFHF 75% FFOF 25%. Just Cal-Mag water. No food. NLS in bottom 3rd of pot. Not wind burn. Not too hot/dry at all. N deficiency? Yellow leaves on first bottom two only. I'm stumped.
