It's fine man. Your girls look good . Lower leaves will yellow and die . There is gonna be alot more yellowing and falling leaves. It's part of the natural cycle.
I'd go with mh/ hps. At least you know what your getting. There is alot of variables when it comes to led. A cheap hps will out perform any cheap led. Just do yourself some research before you buy any light. Amazon has good reviews
Looks like your light is far enough but you look like you have a good bit of heat stress. I blow a small fan directly into my hps. It works for me . I would water heavily and reduce the heat asap
I would go with the vault in UK. Great selection and customer service. The dank team is in Michigan. Fast delivery but they are pricey, and you don't have to worry about customs
