Two different strains in your diary, one is a quick version the other is a automatic.
I don't know what one is in the photos but they look like they are about ready.
I think your grow could have used a better light source, they have stretched so much and the bud sites are on the smaller side of things. Might want to look into purchasing a proper grow light/tent if you continue in this craft, you will notice a large improvement in the quality of the buds.
I use Trichomes as an indactor for harvest mainly and Pistils. Note that sometimes trichomes are ready before pistils are browing, and in other times the pistils are all dried up before the trichomes are ready. This are all based on environmental factors. A really dry flowering room will cause more dried pistils prematurely especially if a fan is pointed at them.
Good Luck!
