What are you growing in? Are you feeding your plant, if so what, and how much? What is the pH level of your water / feed going into your pot? What is the pH level of the water / feed coming out of your pot, your pH run-off level?
Coco, yes I am feeding the plant every time I water. Gh maxibloom for vegging. Ph level of water is always between 5.5-6.0 can’t check run off at the moment and can’t remember what it was last time I checked. Will update in a while
