Hey firsttime, I would suggest you pluck a selection of leafs with trichs on from each plant, then put them under the microscope on a flat surface, and if possible have a look at the colour to know when to harvest (in the FAQ section, there is pictures to help).
If thats not working for you, maybe get a friend to help you out?

Either way, you're plants are looking tasty for bag seed, and happy toking.
WeedyBoyWonder Reviewed by WeedyBoyWonder on . Help me determine harvest time w/o microscope Hi here are some pics at about week 6 or 7 of flower. All three of these plants are bag seed (unknown strain.) The first 3 are form the same plant and I believe it is the plant that will finish first. The 4th pic is of a mutated plant (look at the hook looking leaves and yellow stripes on the hook leaves). The 5th pic is the plant that showed its sex first and looks like it will produce the most buds (weight wise). I tried looking at trichs with a microscope but due to my extreme shaking Rating: 5
