Wwildflower...its hard to tell but Id say 4wks looks and sounds about right, depending on the strain most are 8-10wks, usually 55-65days of flower. The best way is to get a scope that you can check the trichomes(resin glands) they'll be clear right now, they'll start to turn milky, then an amber color, I usually like about 70% amber 30% milky but as long as you got a decent amount turning amber your gonna basicly be fine, farther down the line you'll figure out your exact preference but you got a good 10day window where its not hardly gonna make a difference. Another thing you'll notice is there will be more orange hairs and they will start to recede back into the bud not sticking out like they are now. When you get closer try to post some pic's for people to see and theres plenty of people here that will help you out. Do as much research about the conditions you want during drying and curing it, the main goal with drying/curing is a controlled, slow dry and the cure is just the last process of breaking down and ridding all of chlorophyll while getting rid of the last bit of moisture, a couple week cure will suffice but if you can take some a cure it over a month or two you will notice a difference in smell, potency and smoothness of the smoke, I take my cure quite seriously cause Ive seen average weed become some stank with a good cure, although it will only gain a little as far as potency but it does help as the trichs mature and ripen even more. Hope this helps, get as much info from different people as possible, there are all kinds of different thoughts when it comes to drying and curing, but the one rule is the slower the better just gotta be careful of mould or bud rot,those are the only problems to be aware of with a slow dry mainly. Peace!
