Stem and underside of seedling's leaves going purple

Both the stem and the underside of the leaves turned purple overnight. The seedling is 6 days old in a jiffy pellet. Temps are between 75-85, humidity 30-35%. Currently under about 180w of CFLs and a 250w MH but the latter is too far away to do any damage to the seedling.

Pic 1: from 2 days ago for comparison, green stem
Pic 2, 3: taken an hour ago, stems and underside of leaves purple.

Whats causing this?

EDIT: Sorry double post, the other one has the pics. Ignore this one.

The lest you could have done is put a link of the other post as I cannot find it and I have the same problem as you did! I need to know what this problem is...
Thanks!
