So I am just a few days shy of switching to flower and upon defoliating a bit I noticed new spot on my leaf. I have been using the same tank for 13 days now and slowly ramped my ppm to 600 when topping off the reservoir. It does not look like the same burn I had when I nutes burned them so I think something is starting to drift in the wrong way. Could also be a small nute burn too.
What do y’all think? Using only the Canna Aqua product in my rez, being the Aqua Vega, Rhizotonic and Cannazym.
