They've only been drying for 4 days, so they are almost certainly not ready yet, unless your relative humidity is extremely low. Within reason, the longer they take to dry the more smooth and the less harsh the bud will be, so don't rush it. Usually it take 10-14 days ideally. What is the relative humidity?
As for White Widow, well it depends on which breeder it's from. Some White Widow strains are just hacks, so it pays to get the right one. I would actually recommend you get Mr Nice Shit while you still can. For a strain the costs relatively little you get many seeds and the genetics is the original Skunk #1 from way back in the day. It's also very forgiving for a beginner and I think it would yield higher than many other strains for you personally. If you want something a bit special why not get some Jack Herer?
Anything from breeders like Sensi seeds, Mr Nice etc. will be good. Just stay away from Greenhouse seeds and you're more likely to be successful. I would also avoid feminized seeds. You can sex them using the Genefinder method and pull out the males quite early on easily so it shouldn't be that hard to do but it will also reward you since you're more likely to find amazing phenotypes. When you do find such a keeper, try and keep a clone to make into a mum strain so you never have to buy that strain again. It's what most good growers do.
