It's probably not the wilt-pruf if you mixed it right, or used the pre-mixed stuff.
More likely you have a heat/light/moisture issue.
Don't moisten the RR plugs. They come pre-wetted from the factory and need NOTHING.
Just snip, slice, dip, and stick them in a slot that you have cut into the RR. The hole they come drilled with is TOO LARGE for cannabis.
There has got to be a visual cloning instruction around here somewhere? Last link in my siggy, try that.
Any more questions, post 'em up!
