Strawberry Gorilla Auto

This week is going as planned for 3 out of the 4. One plant is recovering from the early mishap and the other is really stunted. The 2 plants in good health I topped this week and they seem be doing alright, the other 2 plants I plan on leaving as is. I watered twice this week using 1 gallon each time, once with out any added nutrients and once with a tsp of Cal-Mag and Boomerang. The tallest plant has grown to 8 inches while the shortest plant is 3 inches. The lights are at 30% and about 25 inches away from the tallest plant.
