Sounds good. That should do it as long as you're diligent. And it sounds like you are. You might not want to spray when the lights are on though. Not sure about your situation, but mine get leaf burn real quick with lights on and neem oil-water sprayed on them. I always soak right when the lights go out though. Some grows are just fine spraying in the day too. For nute absorption too though, light off and 72 degrees or below is best.
