In coco/perlite. 4 plants, 2 on left side of tent have issues. First one is classic mag symptoms, whether it’s from a lack of mag or excess of calcium, yet to be determined. Second plant looks like mag too but then a few small dots on bigger but not biggest leaves getting light, indicating calcium. Feeding 2-3 x a day @ 700 ppm roughly or 1.4 EC. All fed from same Rez. Except the last 2 days I’ve given the 2 sickly plants extra calmag, 125 ppm starting water brought it up to 450ish ppm then added canna A&B to bring up to 700-750 ish PPm (1.4-1.5 EC) My question is this: if I pour a half gallon of distilled through and the runoff of this is 435 ppm...is it safe to assume my coco is has been stealing all the extra cal & mag I’ve been giving it? If that was the case it wouldn’t show up in the runoff since it won’t be able to be washed out, correct? In cocodelphia, it’s pre buffered & had zero issues last run w/ it, always bringing ppm of tap water to 200 b4 adding nutes, worked like I charm except this time, I left it in the breezeway though in between runs so maybe I didn’t store it properly? And unbuffered it’s self?
