Is this powdery mildew (new clone)?

Is this powdery mildew? I just bought a couple of clones from the dispo and noticed this white stuff on the stem. Iv'r never had powdery mildew so if this is it I don't want to introduce it to my grow room.

I would say if you touch it and it wipes off, spray it with 91% alcohol , increase ventilation and reduce rH.

I got some mildew with a couple clones I got from a buddy and freaked out thinking it was mould.

Well it didn’t come of with just a rub but it comes off if you use your fingernail. Thanks I will try the alcohol trick!

Giv'er a couple good applications and turn your lights down a pinch too so you don't burn the leaves.
