I'm having the same exact problem as you with my bloody skunk. Just stalled right out for about 2 weeks now. I'm positive it's because we gave too much nitrogen. Your leaves at the bud formation are clawed to hell just like mine are. Super dark green too!
I'm growing in coco/perlite hempys and I did a flush + I fed plain water for almost a week. I bought some an big bud which has zero N and I fed some of that for 2 waterings as well. I also read a post saying that removing fan leaves helps when you have such hardcore n tox like us. Something about it removing stored up n from the plant. I ended up trying it and since yesterday I swear I've finally noticed some growth. I'm trying to give it a few days so I know it's not my mind playing tricks on me but i'm pretty convinced I might finally be back on track.
This shit has set my plants schedule back something drastic considering it's an auto lol.
You can see in my pics the plant on the right is way behind the one on the left and they are the exact same age. Got the same exact same feed their whole lives. These pics are 5 days old and that plant on the right still look pretty much the same, minus the fan leaves I removed lol.
Other pic shows the clawing and dark green. CFL lighting makes the color look a bit weird but they are greener than hulks asshole.
N tox is a bitch. Since I fed all my plants the same thing It's obvious my whole crop buds aren't as big as they should be right now. QQ
I feel your pain man, shit depressing me to no end.
