I had 15K (or was it 12?) over my PT when I first set it up (extra from my reef-tank) and although the plants grew OK, I couldn't stand the color. Like on a reef tank - don't like it on a planted tank. Note - the growth here was under the 12Ks (pretty sure it was 12), then I switched to 10K.

Here's 10K vs. 12k - guess which is which (these were taken within 1/2 hour of each other...):
