looks like a lot of glass to me.
i prefer the glass vs plastic assessment. A little amber but majority plastic is the goal. I also look mostly at 2nd and 3rd tier of buds as opposed to the top colas.
if the top colas start turning purple and trichomes are well ahead of the lower buds, i will harvest them before the rest of the plants. Then, let the lower buds continue to ripen. i am not too concerned about any larfy shit at bottoom, it exists... don't sacrifice anything for that stuff.
