Looks more like a fly lava to me, all could be OK but you need to watch the plants very carefully over the next weeks to see

A. if the they start to droop then the lava may be attacking the roots
B. the leaves start to get eaten.

The option is yours, leave it a while and see what happens, keep a fan on the plants as much as possible to stop more pests making your crop their new home.

If the worst happens, you will have to repot and clean out your growing area which I would do as soon as you get chance anyway. It´s a pain in the arse doing this but better than loosing your bud.
