7 weeks flowering, couple questions(pics)

So this plant is a bag seed, been flowering her for 7 weeks this weekend under 150 watt HPS and two 43 watt fluorencents. I was thinking about flowering her for about 9-10 weeks so I was going to start flushing next week or the week after. Is there any other way of telling when the plant is done besides checking the trichomes since Iam too broke to get a microscope and not sure of any were to get a decent magnifying glass. I heard that if you harvest too late the trichomes lose their potency. Im sure the time that this happens differs between strains. I was wondering how long I should let my plant flower just to be safe?

when all the hairs all brown and r starting to go curl into the bud

those need a few more weeks

DO NOT WAIT FOR ALL THE HAIRS when 75-80% of the hairs ar brown/red its time to cut by the time ALL the hairs are brown thc has already started decreasing

The window to harvest is usually only a week for peak potency.
Get a handheld microscope and look at the trichomes if you're shooting for peak potency.
