So after trying to battle Aphids with hard water and soap, which seemed to only chase them to the next bush, I hit my plants with the systemic insecticide that cleared up another one 6 months ago. That plant dropped a bunch of leaves, then didn't bloom for months.

The most infested plant has dropped all its leaves, and the other badly infested ones dropped most of them, the rest seem fine (I applied the treatment through the drip system).

A few days later, I put miracle gro through the drip system.

I am unsure how often I should water them or otherwise take action to make sure they survive. The only reason that I am concerned, the plants were purchased SMALL (1 quart containers) a few months ago, and the leaf dropping plants were only about a foot tall. I have used rooting hormone for transplants on them twice (transplant, then a week later, as recommended), and I fertilized them a few weeks ago as well. They also have a slow release fertilizer with them, but without rain, that's mostly theoretical.

Should I water (via drip), daily? Or should i cut back watering? I am worried that the plants are stressed between Aphids, no water for two weeks (construction blocked access to the hose for them), and now this treatment. As long as the plant lives, I don't care if it takes it longer to grow, just want to get through this.

I've seen more mature hibiscus drop all their leaves and survive, I'm just concerned that these aren't mature enough to make it.
