Hi there GrowCam, that looks like pH-related issues to me. "How?" might you ask , well turns out the pH perfect line has a lot of pH related issues. if you're already feeding at 6.3 you should be feeding lower, like 6.0... after all what is the pH of rain water ? (it's 5.5!) so when the pH perfect is in the soil it causes the pH to rise too much. This you can confirm by measuring the pH of your outflows. if it's any higher than 6.5 than you're way to high. You want to try adding something to stabilise your pH, like pH+ or minus, humic (my favorite) or fluvic acid, either that or beneficial bacteria that will over time stabilise the whole thing. Does that make sense? Hope this helps ! ๐
