Its too late to use any type of fungicide since the breakdown of the chemicals is minimum three weeks. You're going to have to take a tough decision here. If its going to rain for the next week then I would say wait for a short break in the weather and pull your plants. Get them to a spot where you can dry off the rainwater quickly (in 5-6 hours or so) and then dry normally. Keep cutting the mold - it can mush whole colas in a few days.
