Blotchy dark green leaves after flush and nutes

Edit: the bug sites are going dark from previously being bright green. Most of the plant was bright green besides the bottom where it had begun going dark from early on. I did the flush and added nutes hoping to fix a precieved nitrogen surplus but it seems to have maybe made it worse?

To me this looks like your plant is going through a hormonal change and it’s getting ready to flower. It’s normal for bud sites to start going a brighter shade of green when she goes into flower mode. I see you’ve been flushing and stuff too trying to fix things. Don’t stress out too much it’s still a very nice plant. Look at my diary of Jane. She’s had her fair share of problems but still gonna yield me a nice bit for one plant. You’ve got yourself an autoflower too so you’re in that window. Good luck the rest of the way.
