Hello Guys.

Do you have a anything to magnify the trichomes?. most strains that are meant to go 8 weeks will normally go longer. There are a few that can be harvested early though. check for a cloudy/amber mix for a nice body/head hit.

If they trichomes are mostly clear then yeah you got a few weeks left till harvest.

imho the leaves look fairly normal for this stage so dont worry too much.

If you are using soil and happen to have epsom salts then that will clear up most common deficencies and will sort out yellowing in early-mid development.

This close to harvest you have nothing to worry about, except for your patience being tested that is!

Good grow man.
peace
