You have 2-3 weeks left. If you cut that now you'll loose all your weight. Maybe this can help is you haven't seen it.
As the plant matures the new calyx (flower) will form making new pistals (hairs). As each calyx ripen the pistals in those individual calyx will shrivel and receed back. You're going to see a bunch of new calyx form with new pistals that shrivel, that's what makes up the bud. When it comes time to harvest you're going to be looking for a number of things at once, not just the trich color like everyone says, there's more to it.
Here's the order the plant matures so you know what to expect-
1. calyx and pistals form
2. pistal hairs turn color and shrivel back to calyx which will have started swelling
3. calyx swell with resin
4. **Now is when to look for trich color**
The trichomes can start changing color from the time they develope so you can't rely on just that to judge harvest time and pistals have nothing to do with it since they form and shrivel up up until harvest.
Your plants ar about to swell over the next few weeks so be patient or it'll be a waste of time.
