Hi mate, good luck with her. Using the led lights will give you the best spectrum over any other light. There are a lot of research papers out there about using UVA/B in the late stages of flower to boost cannabinoid production. Get yourself an Agromax 20w reptile tube. During flower, start giving her 10-20mins of UV half way through her light schedule ( to simulate high noon). Increase this little by little so not to burn or damage plant. I've been playing with the idea of doing this throughout the whole grow period as UV is present at all times in outdoor grows. Ease her into it as I cant stress enough, too much at first will damage the plant but if done right, its scientifically proven to increase THC and other cannabinoids. Hope this helps ✌️
