Expert advice needed!

I thought my plants were going to be ready for harvest today so last week i stopped feeding nutes. I've been using plain PHed water to flush them. I thought that by todaysome of the tricombes would have turned amber and be ready for harvest. I was wrong. I've been flowering fo about 10 weeks, 80% of the pistils hair changed but not the tricombes, they are either milky or clear. The plants are looking under-nourished as expected.

My quetion is this; do i chop them anyway or start feeding again and continue to flower?

Your advice is much appreciated.

Is it indica or sativa?

Give them some nuts and wait.. depends on strain on how long it takes.. some take 12 weeks or longer

Not sure. They are TNR

well if volume of trichomes has turned milky it is time to make a cut, the pistil hairs turns brow sometime very quickly and is for that reason a bad indicator.
i would start to feed that plant again lightly so that the production kicks in again and stay this way for the next 14 days and check the trichomes color frequently
