My Brassavola Grandiflora (possibly Nodosa) has none of the purpleish coloration on the leaves that I've seen on many flowering nodosas. The whole plant is a uniform deep-green. Is this normal? I suspect I'm offering it to little light, currently it is getting about 1400 for 13-hours from two CFLs and a dose of early morning sun through a roughly east facing window. Should I up the light?

The plant may have bloomed in the past but I've not been able to get it to bloom for the last 7-months.

I've tried searching, I swear!
