My shrooms started to grow about a week ago; but I'm afraid it is not going as well as I expected. The biggest ones are now about 5 cm in length (about 2 inches); and there's only 5 or 6 of the big ones. The rest of them are still very small. And some of them don't even look like shrooms; they have some very weird shapes. Do you think I should pick them now? Some of them started to open the caps, so I think it's time to pick them, but there are still so few of them. Here are some pictures. Shoudl't they be growing straight? Why are some of them so curly and twisted? Is that normal? Does this look like a kit that's gone bad? I appreciate any comments.
