Should I use less blue light in my grow to speed up growth of the plants?

Don't change anything, they look great! Don't over think either, they are still young. The height means nothing at this point, they are healthy and strong not over watered. All good!

Hi buddy! As others have said earlier, your plants are doing well. Blue light is actually good for stimulating growth. Good luck!

Plants are still little babes, changing lights won't really do anything unless the light you have isn't producing enough light. They look healthy Just have some patience 😊

I would leave them be ... At this stage they are focusing on root growth so visually you won't see much growth until this process is done even if you switched the lights. Once veg starts you'll notice daily growth. Hopefully this was helpful and remember Happy Growing and Free your mind one puff at a time.
