Very few strains finish before 8 weeks
Even 8 weeks can be too early for some.
At 7.5 weeks I’d say no however we need a macro shot of the buds trichs ( not the ones on the leaves as they turn early ) to fully try help

That said of the eye ( there are some things to help figure without a scope ) there not ready yet & I don’t think they will be at 8 weeks exactly kinda looks longer than that

You do need a scope to check the color of the trichs to tell properly once they get nearer
