stains on my sheets

Well 1st I think you need to get the clawing fixed and that problem will fix itself. As it looks really bad it wouldn't surprise me if you weren't in nutrient lock. So you could or will be facing many issues Restart the feed. *hard flush that shit Or soft flush with just water for the next week, either 1 me, I'd want to get rid of that toxicity in my soil. So I'd hard flush and restart on a much lighter diet and look to new growth as them leafs look like they've had it, and would break if you bent them cause of N tox? If so, they gone and don't be worrying about what appears on them. But either way, alive or dead you need to pull back on feed for a week or flush and restart it Good luck.
