Our ratios are very similar. I used to run P fairly high myself at the suggestion of a commercial grower I speak with. Usually around 60-65 ppm. Then I found the articles by Dr. Bugbee, and a few from the university of South Carolina that states cannabis will front load P from early veg to use when needed in flower. Don’t want to supply an excess so 30 ppm it is for veg with plans to bump up to about 40-45 around week 4 of flower. Awesome to find another salt grower. I can talk elemental ppm and ratios all day!
