Weezy90answered grow question 6y ago Hey!
If your lamp has the option to switch, light specifically for the growth period and light more specifically for the flowering period, then choose based on where your plant is at right now. If you have a button to grow, then select that now. I used a lamp that had the combination, I couldn't switch, so I had both white, blue, and red light in every stage of my plant's life. I never had a problem with that, so I think it's fine if you have both buttons on. And I also had a 600 watt LED lamp, just like you. But if the function is on your lamp, then yes, I would use it.
I hope I can help! 🙂
Good luck with growing 🌱
