Effect of LED shoplights on tomato plants

[rwsacto]

I purchased two LED shoplights for the garage but set them up as grow lights for tomato season. Tomato plants were potted up at second true leaves. The tray on the left was placed under the LED lights for about two weeks. The tray on the right was under T12 and CFL lamps for the same 2 weeks. Both were raised in 50-70 deg temps.

The plant leaves under the LED lights are visibly more bluegreen with dark stems and more purple underneath. Otherwise they appear the same for size and vigor.
A few LED plants had mottled yellow on some leaves in the third photo.

From now on, the trays will be rotated, mostly under the fluorescent lights, until set outside.

Any observations or comments are welcome. Again, these are 4 ft. white LED shoplights ($25 at Costco), not LED growlights.
