Is it time to harvest?

I have 3 indoor plants all together and I'm in my sixth week of the flowering cycle. 2 of the plants are indica and one is a sativa. I dont have a microscope and i know they're cheap but there isn't a place to get one where i live. i have a 6 light bulb fixture with 4 hps bulbs and 2 mh bulbs. can anyone tell me if these plants are done yet?

It looks like it need a little longer...maybe a week?

Are you counting 6 weeks from 12/12 or 6 weeks from flowering start. They appear to be only around four weeks into flower to me. If ou have no way to get something to see the trichs, yu can go by hairs (I dislike this method). When the majority of theplant has changed color and have recessed it will be just about done.

yea bro this plant is far from done im saying at best 2 weeks maybe 3.

they look awfully green, and not alot of trics....whats going on there? nutes and strain?

i would say 3-4 more weeks AT LEAST

this is 6 weeks from 12/12. im actually not using any nutes just some miracle grow with food in it already. i know miracle grow isnt the best to use but i was on a tight budget, which also explains why i havent used any nutes. thanks for the replies.
