Macro Pictures of My Plants - Are the First and Second Plants Ready to Be Harvested?

Are the first and second plants ready to be harvested? I took these pictures on September 27th. I know the third and fourth plants aren't ready. I'd like to harvest when the tetrahydrocannabinol (THC) is at its peak, but also receive the largest bounty possible for that harvesting style.

from the pic's I would say a week or two at least.

ya they look very small too give em a week or two

I've noticed as the two plants have matured that their leaves near the budding sites have turned purple. Do you think they look sativa, indica or hybrid? Also, do you think it's impossible to tell what strain(s) these plants are?

Where are the fan leaves? They are an important part of the plant's ability to process the light and store nutrients.

Fallen off in winds/died.
