Its hard to tell from your pictures. Add some more light when you take the pic next time and it will make it easier to see. Proper nutrients will help in developing bud sites and i suggest barely letting the top soil get dry. As for bag seed, its a catch-22 because when you buy seeds you have an idea of flowering periods and what not; your situation is more of a guess. Just in case you are not familiar with ordering seeds, you can purchase single seeds for under 20 bucks shipped and let it grow out as a mother for clones. This will allow you to perfect your technique over the course of a few grows with the same strain. From the size/structure of the leaves i would plan on a 7-8 week flowering period. I start that count down after the transition phase is over (about two weeks between veg and flower when rapid growth occurs) and keep in mind you will need to flush for 7-14 days depending on your nutrient regiment. Expect a 1/4 to 1/2 oz depending on lights and nutes. Good Luck.
