sorry mississippi steve. i took all those courses, i must have not been paying attention or something. so i still don't understand how much im supposed to give my plant. 1/4 strength while its young right? so does that just mean i take the maximum (1800) ppm on the chart and devide it by 4 and thats how much i give my plant?
Sjapp Reviewed by Sjapp on . What does PPM stand for? on the back of the advanced nutrients i bought some advanced nutrients for my plants, and i don't know how much to add to my water. Sensi Grow (Part A & B) This website has the table that says how much to mix, but i don't know what ppm stands for. please help Rating: 5
