Depending on how fast they are drinking, sounds to me like you are overnuted. You still have to count your 200 so your ppm is 1400 total. I dont get that high in an aggressive flower. Drop ppm down to about 700-800 and things will be different. You might also be seeing slower growth because of this.
tinytoon Reviewed by tinytoon on . ppm and ph rising I am in an ebb & grow 55 gal res. mid vegetative stage. My ppm is 1200 which includes my water which is 200. So my nute ppm is 1000. I am using House and Garden nutes my ph goes from 5.8 to 6.8 or 7.0 and my ppm goes up about 100-200 per day . What is going on? Rating: 5
