I was running the light at 50% at first and started to see some plants stretching. On day 4 I increased the power to 60%, or so I thought. I turned out I had set it to a bit more, and this girl and one more started to show warped leaves. So, I turned it down to 60% again and moved these girls closer to the corners where the light is less intense.
On day 4 I also installed the auto irrigation system since I had to leave the house for the weekend. I feed them every 6 hours.
The light schedule has been switched to give them night in the afternoon since we have some seriously hot weather during summer. This gives them a day temp at 30-31 degrees C, and a night temp at around 25 degrees.
