They don't look like crap at all. It would be easier to judge how close they are to being done if you would pull the plants out from under the light and take some pics.

To truly judge when to harvest you need to get a scope or jeweler's loup and take a look at the trichs. All clear, not ready, some cloudy some clear, take a test nug to see how you like it.

The further amber in the trychs you go the more couch lock the buzz will be. But be careful, don't go too far, 30% amber should be about your limit. Go to much further out and you'll start to lose potency.

Really, you need to grow a pheno a few times to find the perfect harvest time for you. Did you keep cuts of this plant?

man, they look just fine don't let yourself down!

get one of these:

from this site i bought this very one. it came after 2 months from hong kong but the shipping was free! maybe you can get something faster (and most likely more expensive)... :-)
(be careful: once you start to magnify you can't stop! you'll discover a whole other micro-world you didn't know existed, expecially when stoned :D)

do you have a grow guide?
you need information about trichomes.
you call them "resin glands" it's the same thing. the proper name should be "glandular trichomes". basically they are the means of the psychoactive substances in cannabis.
they look a little like mushrooms...
i found this on sensi forum, very helpful:

the thing is: as they mature they will change colour.
at first they will appear small and very clear, transparent.
then they'll get bigger and "cloudy" as melvan says... cloudy means somehow whiteish but no longer transparent. when they turn amber they are at the last stage of maturation.
so, when melvan says "your limit is 30% amber" she means to have 30% of the trichomes amber (and probably most of the remaining 70% would be cloudy).
if you know a particular strain and a particular phenotype of that strain, you will know exactly at which point you have the desired effect.
petrolss explained to you in the other thread: gather information about cannabinoids (it's chemistry) and how maturation effects them.
i read cervantes' "the bible" (the real name should be "the indoor-outdoor medical grower bible") it explains well the argument, but there are many readings you can do on this matter.
also you'll find on youtube some videos about all this.

good luck, and don't be scared, you'll have a good time!
best

what strain is that by the way?
skunk #1?
superskunk?

Hey, hey..
