I don't think the light makes all that much difference, frankly. I currently use a 6500K LED bulb, but previously used one at 5000K and one with 660nm Reds. Guess what? No difference in growth. If your chaeto won't grow I think it's far more likely it's lacking a key nutrient. Neither nitrate or phosphate is the likely culprit either. Probably iron as was noted earlier.
