Good job getting them this far! Time for you to start planning and prepping to harvest and cure. I'd wait for a more experienced grower to confirm, cause I could be wrong, but I'd say your in the harvest window. I'm not seeing a lot of clear, some amber present....
Seeing a bit of amber, if that’s what you are after. I rarely concern myself with the “colour” of the trichomes, but rather the swell of the heads, and as mentioned, I would say you are in the window for harvest.
fan leaves have stems, the sugar leaves do not... don't worry about leaves anyways but look at trichs on the calyxes, if helpful snip a small section of side bud calyx to view under your scope. I can‘t hold it still enough to see unless I use table for stability.
I do see some amber representing, granted it’s slower that trying to get a slice of leg but worth the wait. As TheCelt said look at the swell of the heads too for an important cue. One day your sample will be filled up with reddish hue too. As Rexer said you are in the harvest window - you could go longer or depending on your goals and plant structure you could do partial harvest & get top colas chopped and locked in and then let the rest mature for another week or two.
The main part is for you to see and learn stuff as you go - you’ve done a great job so far! Keep up the good work.
I believe you are in the harvest window. I think you could wait another week though, i see some clears still maybe theyll cloudy up and youll have a few more amber
