I see a few leaves starting to canoe. It's because you've maxed out your feeding and watering for the amount of light you have. Congrats.
You have two options;
1. Like they've mentioned above, turn down the lights a bit.
or
2. Increase air circulation considerably. A strong fan above and one below should do it. Note that by doing this, you'll need to increase water/feeding at some point. It's a crazy cycle.
Personally, I'd just decrease the lighting. In a commercial environment, you'd be pushing it hard with more air flow, feed and water to max out the yield. On only a few plants, you wouldn't see a difference pushing them that hard. But on several hundreds you would. It all adds up.
