6 weeks into flower...no trichomes :(

Wondering if anybody can give me a diagnosis on this, I've got lots of bud happening, but not too many trichomes, a LITTLE noticeable on some of the bigger buds, but they're not on a large portion of the leaves. Should I be concerned? I had thought I'd harvest in the next week or so, but should I keep these going longer? Sorry that I don't have a better close up, but hopefully you'll see what I'm saying

Only 1 plant on a 400w HPS

i would say you have a nute deficiecy, just guessing nitrogeon and magnesium. I think you have atleast another month to go.

as for trichomes, maybe its not a good strain??? i think by now you should see a good bit of trichs on the buds. its not so bad if theres not many on the leaves but im sure in a few more weeks it will get better xD
