No, phosphorus deficiency starts at the bottom of the plant. Are you in soil or coco coir? Can you tell us what the pH and PPM of the runoff are? Also, what light are you using and what is the distance from the top of the plant? Any signs of pests?
I did notice small brown spots Friday that’s when I moved it and I had to go out of town for the weekend and that’s what it looked like when I got back
@Mr. Grow It would it be easier to use coco coir ?
No sign of pest I also had the SF1000 but I’ve turned it off
