Too little light

Roma Tomatoes

It is getting taller and more leaves but is to thin.  This is an indication of the plant reaching for the light.  If used it will have to be propped up.  The 10W 6500K light is too weak, will hit the Home Depot or Lowes and look for one several times stronger.  This plant can be saved by moving it to my outside garden.

Lettuce

The lettuce is also suffering from lack of light.  When I built this array I never calculated the amount of lumens it would produce.  This array only makes 5.6 lumens which is not good.  I drew up a new one last night which will be a blue only array.  With the LEDs used on the new one it will produce about 857 lumens which should be enough for lettuce.
