Damn it that sucks that first one looks to me like a male thats what I saw for my male I kept it around I actually still have it and its been about 3 weeks knowing its a male, but I am letting the pollen fall onto some black paper to collect the pollen. That sucks but then again you dont have to order any more cause if you pollenate the lower branches you should get enough seeds but not to much to were it takes over the bud growth. UGH
Its definetly a good thing the other one has no preflowers especially if its from the same strain that usually means that its a female. But I will be hoping and checkin in that you find hairs in the other one.
I gotta tell ya that the first time I saw hairs I jumped and was screaming lol it was pretty funny how crazy I went for hairs on a plant, but I was sooooo excited. Then I would look every day to see how many hairs I could count. Now into the end of the third week I look at it only a couple of days a week and every time I look at the 2 females now I see a lot changing and growing..... yey! we gotta hope your other plant is female i will be checking on your thread daily and hopefully i will get pics up soon of mine and you can check out my girls till you have your little lady
