Well, no slime of any kind I have seen anyway. I went and looked pics I shared to see what you are talking about and I believe you are seeing the green markings from the outside of the pot. There is a green band right about where soil tops that goes all the around pot. If not then please elaborate.. I did however find the problem it was the damping off due to fungus nights. I had transplanted one of my girls in apparently infected soil which then spread to the rest of my girls. I think its completely fixed now but staying on top off it. Washer, dryer, stove, table whatevers handy. Thanks for the feedback
