I think somewhere between now and the next three weeks, but more towards three than less. Looks like ten gram cola or so? Hard to tell weight even when you have something to compare it to size wise. Looks pretty good and IMO no worries on the trichs, you want to be looking at your pistils before your trichs. Once your pistils turn orange all over or at least the majority then you should see the calyxes start to engulf the pistils as they start to redden. This is when you'll want to really start looking at your trichs, at least in my opinion and on some strains the colors that the pistils will change varies but they will all have stages of ripeness. Once you grow the same strain you will know what to look for and know when the best time to chop is. Good luck.
