Day 44: Rust spots showing up all over the plant. Should’ve guessed it first from leaf tip curl/bending. Nitrogen toxicity!
Flushed plant with 3.5 litres of pH 6.5 water. Runoff pH was 6 and EC was 2.4 at first. Brought it down to pH 6.3 and 1.6 EC. I hope I solved it for now.
Day 46: I still see Cal/Mag deficiency. Not sure if lockout still persists? I’ll avoid Bio-Grow for sometime
Day 48: Flushed it again with 6L of pH6.4 water. Initial runoff was 2.56 EC, 1200ppm and pH 6.1. At the end it was 0.8 EC, 650ppm and pH 6.3. Added some CalMag and Bio Bloom after that. i hope it gets better now!
