Calcium deficiency? Discoloration of leafs, brown spots, yellowing

1stly, if you are getting run off.. That's your issue. You are letting the soil dry up too much If your plant is needing water, she'll eat the closest part to the roots. Your lower leaves If it were a full on issue. You'd see it more up top Soil should be not allowed to go that dry. Yeah, u can crop steer by drouth to the soil but the plant shouldn't be allowed to feed on herself That's what I see here.. Just keep the bloom NPK 5-10-10 (ratios can show 1-2-2 same thing) ph is good. Just keep the soil moist 2 small NPK feeds a week. Add Epsom Salt for mag/sulphur (its the best mag you can add) Cal should be in any good bloom nutrient. If needed add 1. But I think NO RUN OFF, there should be none with soil. There's no need for it pal, also you need a ph soil pen, you can measure true ph from sol pens. Soil takes the PH into its base and running water thru it will just give you dif levels the more its flushed..
