Powdery Mildew?

When did they switch over? Just a few days?

Just a guess based on symptoms...What is your humidity reading? Do you see any white specs appearing on leaves?

maybe the heavy feeding was just too heavy. Since you've flushed the plants i would let the soil dry out so that the plants can kick back. When introducing a different nutrients I try to start it at lower levels.
