Neonicontinids are no longer available for home use, at least in California - I am not sure of the limitations for commercial use. So their indiscriminate use is definitely bad for the environment....

Water that runs through the pot is ideal - it pulls air into the root zone while it's hydrating the roots. And it's really moist air, not "wet" that they want. That moving water also flushes out...

I'd suggest moving these to the north window, at least until fall - the fall/winter sun angle is lower so there will be less chance of sunburn in the afternoon. Phals really are low-light plants....
