Looking at that link, they all look very bleached. How long is your light cycle?

Dusk to dawn (4x54watt T-5) 7:30-8
day lights (4x54watt T-5) 8:30-7

That should be ok right?

My bulbs are as follows

4x ATI Blue+
2x ATI Aquablue special
1x Giessaman Aqua pink
1x Giessaman Pure Actinic

Might be a bit much. I use about 7 hours of daylight, seems to work well. With too much light, they can over oxidize nutrients at the cellular level, causing bleaching. I'd maybe back off a few hours and let them darken up, then reassess from there.

So.....is my dusk to dawn ok? or should I be backing that off as well?

Depends on the intensity of the light, I'm not familiar with T5. I use a single actinic from 8am to 1:30pm, then daylight until 8:30, then back to the actinic until midnight. Works way better for me over my previous 10 or 11 hour daylight cycle. Saves on bulbs too.

This may be a stupid question....but if they were bleached....would I suddenly experience a growth spurt?

The last 2 months or so my other SPS's have been growing by leaps and bounds
