your plants look like they have at least two weeks of getting fatter and building cannabiniods. touching trichomes will crack them and cause them to turn amber and may be confused with degredation but that generally wont start until your pistols are atleast 90% tinged.

your more than two months into flower i would guess you have a 12 week sativa dominant plant which should be a good head high no matter what stage its pulled but your only cheating your self by pulling early the quetion i guess should be

how high do you want to get

i just did twelve weeks on some gdp that looked like yours after 2 months i thought it would never finish so i pulled one to test and in two weeks of being ready it doubled in weight and strength. i know your eager to start rd 2 i would be too but please take one ALL THE WAY please if not for the sake of more stronger better bud than for the science and the experiment get a good weight figure.
