How do I feed using a TDS meter? I have obviously got some signs of under feeding and am trying to do feeding by PPM as on the coco nutrifield bottle it says the 20ml per litre for A and B solutions and feed 4-6 times daily for 3 minutes. Since I am top feeding roughly 10L per plant every 2-3 days I am unsure how much to feed i measured today and what i typically feed is 140ppm per 10L which is in the seedling range. Can I just increase what I feed every two days to 450 slowly increasing too 700ppm? Or what is the best way too feed plants this way?
Thanks any help appreciated!
