Just once. Some growers finish with a dose of molasses. (1 tsp per gallon of properly ph'd water, once a week) But if you don't add nutrients after the flush, one flush is all that's necessary. (usually a week or ten days from harvest date is fine) Let the soil dry before the next watering though. You don't want to end-up with root rot from keeping the soil too moist for too long.

Until you get a bit of experience under your belt, best not to stress the ladies with a mid-flower trim. Low-stress training (bending and gently tying) can be done almost any time if you don't go overboard. But the stems will start to harden-off making the training (bending) much more difficult.
