lol, get more magnification on that scope! your eyesight really shouldn't hold you back.
don't look at leaves.. ignore leaves.
Trichomes on calyxes are not easily visible with these pictures. But, i see long white hairs still, meaning there's plenty of plumping remaining.
sometimes trichomes don't amber up... at that point you use other physical oboservances to make the choice. Your plant still has ripennig to do... nd even after that finishes you probably have another 5-10 days.
density, pistil coloration are 2 observations you can use to help choose a harvest date. Be patient. You spend ~100 days growing this plant, so a few more is no big deal.
I'd let those calyxes plump more fully around the pistils (white hairs) and then re-assess at that time. Look for a cheap 30-60x currency checker or jeweler's loupe... some lie about magnification, some have a plastic lense... you may need to look at several options on a site like amazon before you find a suitable one. Only scope trichomes on calyxes...
if it is ever fully ripened and trichomes seem to never change to amber.. then you consider harvesting using other visible obsevations. It's just something you have to do a few time to get comfortable with it... being off a bit doesn't ruin anything completely, but like is aid.. you invested all this time, might as well do it right. be patient.
