yeah, I thought so as well a bit after my last comment, so I went to work on the darkest one. It doesn't look so bad as I had feared when the leaves are cut away. I almost haven't used any fertilizers products at all, so they are almost already dried. (and I've read somewhere that it's only when using fertilizers you need to flush) It's like a have skipped a step because of this...but they aren't that big...
