canniwhatsis Reviewed by canniwhatsis on . Mg deficiency or Rust fungi!! Alright lets start by saying i started noticing this on one of my plants about 2 weeks ago. At the time i was give a full dose of FF Grow Big and Big Bloom. I water with R/O water and everything is always buffered to 6.5-6.8 pH. Runoff is 6.2-6.5 pH. Last weekend I up potted everything to 3 gal pots using FFOF with 20% perlite added. Tuesday i noticed that it had moved from just the one plant now to almost all. At first i thought it was a Mg def. so I added Cal-Mag 3 days ago, but now Rating: 5
