Are your lights movable? If not from one of the pics it looks like you are going to have some height issues in the next couple of weeks. If it is your first week of flower, or even 2nd, they have barely started entering their stretch... Also for pollen collection, you want to wait till the pods look like they are just about to burst. If you want observe a few of them go through the process of opening up. Then you can judge when you should snip the ones you want to save.
