How long do I have left on this girl?

first time grower. How far along does this bud look in terms of development?

You still have a good few weeks in my opinion

Let her keep going, she will fatten up and those hairs will recede into the bud a bit. Also they may turn orange/brown. Try to get a closeup of the crystals, they will turn amber/dull as they mature. Brown/black is bad, you want a lot of amber in the crystals.
