Browning leaves

this plant has never had this issue before what is this usually a sign of?


Looks like nitrogen toxicity. Do you know your runoff PPM?

I do not, ordering a ppm meter right now. all i know is it has increased due to a new air pump. what should it be at?

1,000 to 1,200 during flowering. I expect yours is much higher. You have nute burn. I would back off the nutrients and maybe consider a flush. Burned tips, clawing leaves, and dark waxy leaves are all symptoms of too much nitrogen.

Is that a hydro setup? My ~1,000 (and the flush comment) comment is for soil only. Iā€™m not sure about PPM levels for hydro or DWC of some type.
