Where"s the trich?

I have some Satvia plants, and this happens for the third time. They get looking promising like green coral with lots of little buds and then just turn dark and nevr really form trich, any suggestions? Ive been using Bontanicare Pro Bloom and Liquid Karma. Thanks Buds (cool pun huh)

Some sativa strands have little visible ones. Yet the bud is still potent. Hows the smoking? End result is what matters. I have grown some weak looking buds and they turned out some of the best. No joke.
