I'm lost, lol,, ok, are u saying as the plants use the nute's your ppm is goin down so your adding micro and bloom to compensate and your ph is going up? Your question is confusing, when ever you add any nutes, be it micro and bloom the ppm will go up,,

What are you running( growing in)
If you are doing dwc or flood and drain, the plants will consume more water then nute's. As the water is being used and evaporated the ppm's will climb causing ph issues. Just top off the resivor with more water. The ppm's will drop back to normal but you may need to adjust the ph,

Sounds like this is in the wrong section. This question would make sense for dwc, not drain to waste.

If it's drain to waste, idk what your asking.

If it's dwc your plants are taking up more nutrients than water. Meaning you need to up the ppm until it doesn't change but the water level continues to drop. Your plant would then be using the same amount of water vs nutrients.

Yeah wrong forum. Drain to waste means your running a non recirculation system were your runoff is not recovered.
