I have been growing some tomato seedlings indoors and I have noticed recently that some of the leaves on a few of the seedlings have gone wavy. I bought a grow bulb that I put on for about 15 hrs a day, and it measures about 11000 lux at the point of the seedling leaves with the light alone (when the sun is out it gets about 18,000 at that distance from the light. It’s basement window haha.)

Am I getting too much light? Or do I need to water more? Or am I worrying too much?

Here is a picture of the tomato seedling in question

They look fine to me. It’s the first set of leaves, so it’s just what the plant needs to get started. At this point they look very very healthy, especially with the new sets of leaves popping out just now. If they were outdoors I’d tell you to check for bugs like aphids or mites or other small critters, whenever they bite young leaves it makes them wavy. But these don’t show signs of that.  If anything I’d say those first cotyledon leaves are wanting to be true leaves already!
