Brown spots and color change on one of my plants

The yellowing would indicate a nitrogen deficiency, which is normal during flowering. The browning and interveinal chlorosis may indicate a magnesium deficiency. Might also have a phosphorous deficiency.

It is hard to tell in the picture, what medium are you growing in?

I wouldn't worry about the nitrogen. Maybe supplement with some calmag and bloom nutes. Rest of the plant looks healthy overall.

Ok that's reassuring. I am in soil foxfarm the brown bag. Feed envy part a typically i feed, then water, then water, then feed 2 days apart. Should I adjust this and maybe feed water feed water thanks for your input

Are the stems of the fan leaves purple? It looks like they might be in the picture. This would make me lean more towards a phosphorous deficiency. I'd fix that first and clip the really the bad leaves.
