Long ago I used to run coco….. did it all wrong. Went to soil for a few years and now back to coco. With the ppm side of coco everyone seems to suggest keeping the ppm low (450-600). With ro water I’m running silica blast, calmag, liquid karma and pure blend pro grow and bloom. By the time I add everything there’s only room for 200 ppm of grow. Doesn’t seem right to me. I’m getting 2 parts n from my calmag but it doesn’t leave much room for the other macros. I’m flgetting really slow growth. My roots look nice and healthy but in soil my plants would be 2 times the size by now. Any advise? I have a 3 week old seedling that is a little pale and some twisted leaves. No burning at all but a little pale like it needs more food.
