Broken Lighting
I have a 4 bulb Odyssea T5 fixture with all 6,700K bulbs. It was on a schedule for 8 hr total light, and six of both. A few weeks ago, I noticed that the back two bulbs will not come on. The indicator light shows that they are on, but they aren't. The bulbs are too new for that to be the problem. Does anyone have a suggestion of what could be wrong? Also, I have noticed that my plants are growing thick (as in many leaves) by not tall. Is this an indicator that I need to change the light timing now that I only have two bulbs going. BTW it is a 120G tank that is 48 in wide.

The problem could be the starter or the balest. How many balests are there? Also it sounds like your getting plenty of nm's in the low spectrum (blue) but not enough in the high spectrum (red). I just switched 2 of my bulbs to Rosettes and my plants are huge. I had it explained to me for photosynthesis plants use around 440nm for leaves to broaden and 660 to grow in height. Hope that helps.

My guess is bad ballast.
