I have been feeding them the big bloom once every other feeding I started at half strength and have worked up to 3/4 strength which they seem to like I'll probably stick with that next feeding then go full strength! The strain is skywalker og I read they can flower for 8 to 9 weeks I'm gonna get one of the jeweler microscopes and keep an eye on them starting week 7 and go from there I feel like it will probably be closer to week 9 the lower buds started filling out about a week and a half later than the top cola so I think they still need another 4 good weeks or so but again this is my first time so I'm not 100 percent certain. I'll tell you this going half way through week 4 they are so dam stinky up close they smell like berries but from a far they have a weird dank aroma not skunk like kind of hard to describe but it's good lol
