Strawberry Gorilla Auto

Not starting off as smooth as I'd Like. My plants on the right hand side primarily under the SF-2000 Pro are growing as expected, the 2 plants primarily under the SF-4000 aren't doing as well. It appears I needed to turn down the light intensity some because I am already seeing yellowing and they are not nearly the same size as my other plants. In hopes of fixing this I have turned down the dimmer on my lights to almost 20% and raised both of the lights to 30 inches from 22 inches. I have also adjusted the light cycle from being on for 24hrs to 16hrs, For water I am using about a half gallon of luke warm water spread amongst all the plants twice a week.
