sd6515- that's from touching your flouro tubes earlier. I remember that thread.
whatsthatsmell- didn't you have another thread about this too? That you got htose as clones and they already looked like that? By misting them you are doing something called reverse foliar feeding... in essence, you are leaching out nutrients. If you mist, do it with a complete fertilizer. I don't like to mist my clones once I have determined that thye are rooted. Once they have roots, they can- and should be forced to- take up their food and water that way.
