PPM going up

@EVERYTHINGFRIEDISGOOD because you are not changing the solution it is just building up in unused salts thus the increase in your EC / PPM the plant takes what it needs and leaves what it doesn't and when you just add more to the solution instead of changing it occasionally it certain nutrients build up and cause the high levels So change your nutes out every now and then or risk loss of yield and problematic growing experience 👊
