So you decide to start the fire first, well done. I'm sure you are taking Reaper out of context, and for the record, it's pretty spineless to namedrop in a thread that the person isn't even involved in.

Looking at the pics, my first question is what kind of soil are you using, and what kind of mulch do you have on the top of it. Do you have any idea of the Ph of the soil or water?

If there are any nutes in the soil whatsoever, and the clones have only been in it for a week or so, I highly doubt it's a deficiency. More likely a ph lockout or something causing the nutes to be unavailable. Need some more info to help you out tho bro. Go to the plant problems forum and fill out a troubleshooting form as a reply to this thread. Don't want to tell you anything for sure until we know all the variables.
