Keep in mind, when using quality dry ingredients (like HR does), you don't need anywhere near as much ppm, especially when feeding 5+ times a day.
Nutritionists tell us 5- 8 small meals a day is best.
Probably a max of 500 ppm is sufficient for tomatoes. It is for late growth mj with max of 600-800 for full on flower
You growing Romas, Beef Steak, or Cherry? Would like to try growing some Romas
