the only real way to tell if a plant is ready to pick is to invest $5 in a 30x loupe or a more powerful scope 50x to 100x and look at the resin glands. if the resin glands are still clear, it is too soon. when they turn milky if you harvest then you will get a head high "up" feeling. if you wait until most of them turn amber then you will get a heavy stony couchlock feeling from smoking it. harvest at 50% milky and 50% amber to get a mix of both high and stoned....
