Hey little Buddy, good to see you around.

 

Yeah just ph water you could try a flush on your soil but really I wouldn't. It's better than nute burn, of course it's not what you hope for. One of mine is suffering from the same thing. Switching from pro mix to ffof takes some real adjustments.

 

give only water for a week or more. the green is too dark wait until color is lighter
