Most growers tend not to mix them. In theory there's no reason saying you can't. It may stress your plants though. If you have a look at lighting experiments on yt. You may find your answer.

UV LED slowing down growth? Sorry previous question without the question!
The plant has a rectangular area in the middle where it is not growing as quickly. The difference is almost 10cm. I suspect the lamp. Could it be that the centrally installed UV LEDs are causing this? They should grow more inside because of more light.

Should I substitute sunlight with a grow lamp on cloudy days?
It’s overcast here today and I’m wondering if I should turn my grow lights on to compensate for the lack of direct sunlight. If so, should I drop the intensity to compensate for the additional natural light? Can you overdo the amount of light (not heat) a plant gets?

Would I benefit turning my lights on from veg to bloom at an early age with auto flowers? Or would it still be too much light for them?
