What do you mean no THC?

crystals

Sativas can be a bit of a waiting game, have you got any photos?

Sounds a little early to be worried about not getting any trichomes. IMO it depends on genetics and how far along flower development is. I typically don't see trichomes until end of third week in 8 week strains. But there have been exceptions to the rule in both directions.
