How long until harvest? Total noob here.

Forgot to keep track of days etc. and I'm unsure when i will be ready to harvest.

To tell when your girls are at prime time to harvest, you need a magnifying glass / pocket microscope / jewelers loupe with atleast 30x zoom capability and then you want to look at the trichs to see when they are all about 25% amber and the rest cloudy its time for them to come down, do a search about "harvesting by trichrome" you will find the exact answer you are looking for good luck, nice looking lady don't fall into the temptation to cut early either!!! 50% of your final weight comes in the last 2 weeks of flower!

EDIT- Or if your camera has macro close up ability that works wonders as well for checking the trichs!

You've got weeks to go. It's also not just about trichomes. Take into account the color and shape of the pistils. The hairs will be dark and recede back into the calyx as it swells and "pops" off of the plant in a roundish growth. The trichomes on the calyx itself will be cloudy and maybe some amber, no noticeable clear heads. The plant itself will have a "done" look to it - not as green as it was weeks earlier.
