The rust spots on the leaves are getting worse. I flushed twice and fed with a bit of extra runoff, but a day later and the curling burnt ends look like nute burn. Any thoughts would be great!

Purple spots on leaves?
A few leaves have started showing purple spots, some with pale green/whitish bits as well. Picture above. Any help would be great. I’ve been feeding on the BioBizz schedule every second watering, usually every other/every third day.

Light burn
I've got what I think is light burn. I can't dim or raise my LED lights (300w), but I'm currently running them 24/0. Would switching to 18/6 help? Or would it help to take the burned plant and have it out in natural light during the day? I'm growing autos and they're flowering.

Yellow/brown and crispy lower leaves?
Some of the lower leaves on my Purple Punch Auto are turning yellow/brown and crispy (day57-58). The one pictured has just developed like this—I trimmed a fan leaf yesterday that was in bad shape. Any advice would be great!
