What’s wrong with my lady?

Thought it was light or heat stress but light been at 50% for a week, getting worse. I’m thinkin to much nutes Maybe?

i’m using General hydroponics and following the schedule P PMs around 650. I’m thinking maybe I’ll flush her out the next couple days and see what she

looks like. she’s a platinum Bubba Kush in cocoa in week 8 from seed, 14 days in flower. I’ve never grown the strain before not sure if it’s just nute sensitive light sensitive or what? Any ideas or help would be greatly appreciated
