get a jewelers loop and you will be able to see them. this is a good investment anyways because you will be able to see trichromes. which in turn lets you harvest at optimal time.
or u can get a 60x - 100x handheld microscope from radioshack for less than $10 . ive had mine for a few years now same batteries i put in it works perfectly. i even put a camera on it u can see a pic i took with it in my profile.
your plants kinda look hungry too me. but i would wait for some people with more knowledge and/or experience to back up what i'm saying (or refute it) before u drown them in food.
