it has been like this for 2 weeks

Yeah what everyone else is saying. It's too early. Give it another few weeks. They'll start popping up more visibly. Try looking at them with a jeweler's loupe with a light on it. Or if you have a really good camera, you can zoom in real close and see them that way too.

Yep, too early for THIS plant. Plants in the "transition zone" between veg and full on flowering often stall while they get themselves ready to change the direction of their lives. Don't worry, your plant will soon get into it in a big way and the trichomes will come too.

Too early, but she will start developing them before Long. Your just starting to form buds. I would decrease your nitrogen amount a little and increase potassium and phosphorus amounts. She needs those to produce buds and easy on nitrogen. It can hinder bud development. Good luck and be patient.

I've had a couple of grows like that... you get worried they're not there but they really are... You can either zoom in on a bud (main cola would be best) or get a jewler's loupe or microscope (which you'll need to determine when to harvest anyway) and take a look... they're there... they really are! The other way you can tell is when it starts to smell... Good luck - looks good!
