you still have a couple more weeks. looks like your around 6-7 weeks. you still have alot of white hairs, wait till they turn red or browish and the whole bud has a "goldish glow" to.Tric will more than likely be clear still?
Watch your nutrients, they look a little burned. And your temps, look a little burned that way too.
Better than my first grow, keep it up.
Edit: After a second look, the first pic kind of looks nutrient burned and temp burned. Third pic actually looks like too few nutrients, yellow crisping up fan leaves. Fourth pic looks like it's getting hit from all directions by all of that. Second pic actually doesn't look that bad.
Get a magnifier, at least x60 and check the trichs. There are threads here that discuss the various theories behind when to chop, which trichs you want, etc.
