HELP

Dose anyone know what has caused this? Not sure if its light burn or nutrient burn

Is that all over the plant?
Nute burn starts at the tips.
Try to get a better quality pic of the whole plant, and check your ph.

Good luck

That looks like a plastic leaf from the dollar store.

I guess phosphorus but it's a slightly educated guess.

If you go by the chart it appears to be close.
