Ok thanks Tiny. My plants are showing signs of slow growth and nute burn. I will empty and refill res. with less nutes. I have not changed res. on a weekly basis, trying to go bi-weekly. Tiny thanks for the info on ppm. I didn't know you count your waters ppm. I thought Marty was my mentor, well Tiny is up there in my book now. Thanks Bro!!! I just checked my ppm are up to 1300 and ph 6.7 unreal. ppm rose 200 in one day ph jumped from 5.8 to 6.7
avon211 Reviewed by avon211 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
