DIY ejuice question

hello all, newbie here with a quick question

I ordered a 50/50 pg/vg blend of 6mg unflavored base and some flavoring concentrates and I’m just wondering if that’s enough to mix up some decent juice? I’ve seen hella recipes that use very high nic strength pg or vg bases and mix all the extra pg and vg and whatnot separately. So i guess my question is; can mixing a decent ejuice be as simple as finding the right ratio of unflavored juice to flavor concentrates?

Any input you might have would be much obliged.
