Generally the already affected leaves won't repair, but it might stop from getting worse and new ones won't develop that syndrome. So don't try driving by the appearance of those plants. Just let time and your new solution do its thing. Don't change water for another week.
herbie the love bud Reviewed by herbie the love bud on . EC and PPM I bought a EC/PH handheld meter from Hanna and I recalibrated it using the provided solutions.

This causes me some concern because when I used my ppm scale on the meter in the test solution it didn't read near the 1500 ppm I assumed that it was going to read. HOWEVER it did Rating: 5
