Leaves

Are you putting cal/mg in every watering, dont. Are you feeding by label directions, dont. Ph tds reader and feed by total ec which would be about 1.2 or 3 for this stage, cal/mg when they need it. Dont know if its coco your growing in, if so the it may not have been buffered properly. I would check your runoff ph and ec levels to see where your at now. Ph should be in veg in your medium, 1.2 to 1.3 ec for now, and ph should be 5.5 to 6.0 for veg. So early veg start at 400 ppm, 0.8ec, veg 600 to 800 ppm, 1.2 to 1.6 ec, when switching to flower nutes you drop your nutes back to 1.2 and increase to 1.6 for mid flower and back to 1.2 for late flowering.
