i was just wondering.

i am seeing purple spots develop on my thermometer.. is this the start of cyno. or is it just the progress of coraline... what my real question is, what does the beginning of a cyno break out look like... want to be prepared so i dont make a mistake when it comes

I have some coralline on my thermometer and I`m sure that`s probably what`s on yours.
 
Probably corraline. Cyano can be effortlessly brushed off with your finger and has a sliminess to it, corraline cannot and is hard. Search for pictures of both to be sure :)
 
thanks guys... definitly the wrong color to be cyno... and wont rub off
