Please critize my grow part 2

Hi everyone this is my second time posting since last year. I have another post with pics when I first started my amateur grow. There was much positive feedback from you guys which I am grateful for. This is my 1st time actually growing to the point where I'm actually starting to see results. I took these pictures with a camera phone so I don't think you will see much in detail. However I put these pics up to see if anyone here can tell me when more or less I should harvest my ladies or to wait. Some of the ladies still have to develop but there are a few that are already flowering. Please tell me what you think about it thanks

Can't say when to harvest just by those pics. What color are the trichomes?

There white from what I can see. But to be sure Im going to get a magnifying glass. What color should they have to be before I even think about touching them? thanks

Wait till you get at least 10% amber and it'll prob take more than a mag glass. A 60x or more microscope would work better.

You can get a microscope at radio shack for less than $15. It has I think 50x to 100x zoom. It is great for looking at trichomes!

thx guys for the advice.
