Couldn't tell ya exactly but tri-bands (what I have) are primarily red, then blue, then white I believe (been a while since I bought it) so while most are red, the 2ndary color is blue (thus the pinkish-purple glow). As far as I know they do pretty well for veg and maybe a bit worse for flower (someone else can confirm/deny as this is my 1st grow).

As for yours my guess is that they might be restricted for space if they're still in cups? Or maybe not getting enough light, they seem to be further along in the number of leaves than mine, just much smaller... I'd ask around.
