Gamera said:Hello family. I recently started using Promix hp instead of Fox Farm Ocean Forest and so far it's a wonderful thing. Except I'm getting these rust colored spots on some of the plants. I'm using Botanicare Pure Blend Pro grow and bloom with Cal Mag as directed or less. I'm adjusting all feed to 5.8 - 6 ph. I test ph with 2 probes and for the most part they're around 6.8 - 7 ph. I'd like to get it lower but the Promix seems to have a ph buffer that holds it around 7. I mixed some water at 4 ph, watered one bag and tested the ph as an experiment and still got 7. I'm using Natural PH Down. Whatcha think? here's some pix of the rust.
