How quickly can i give nutrients if im going empty...

High Medes, When you want to provide the plant with nutrients quickly then you need to use liquid nutrients in pH water. You need a basic flower nutrient, PK booster and Cal-Mag supplement. These are all the necessary nutrients for the final phase. Happy Growing Buddy! 💚

I don't understand what you mean But, generally you go by PPM not ml/l. You're using powders. So, when I used them. Generally .2 of a gram adds 150-200ppm to 1L of water. You're coming into the flower phase. So, idk how You're giving your nutrients. But, grow you don't give if You're using it. Just short/long flowering. With pk booster during fattening and even high pk feeds in ripening lowering the bloom as it progresses. If you are using soil. 6.3ph is TOO low..minium 6.5 but optimally 6.7 or around that range is better.
