Quick question about your nutrients. You put 2.5ml / gallon, but each stage requires more nutrients. So does this mean you put more of the nutrient/water solution in? My tap water has ppm of 80, 140 after I add my nutrients. How do I make it 400ppm? Kinda confusing me. Love all your grows and going to go through fast buds catalogue and use your account for reference. You produce some amazing plants
