light order?

I have two t5 light fixtures on my tank. Each fixture holds two 849mm t5 tubes so obviously there are four t5 tubes altogether. My question is can I have two white t5's on one fixture and two actinic t5's on the other fixture so I can have just the blue actinic in the evening or do I need to have white, actinic, white, actinic in that order so its spread out? If I have alternate lights then I won't be able to have just blue in the evening. just wondered if it made any difference? Thanks

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.

so the light would spread out evenly rather than blue light at the back of the tank and white light at the front?

The fixtures should be close enough that they should spread the whole tank. I never noticed any issues with my tanks.
