New to AK47trichomes are all milky with a few Amber's. From looks alone how much longer until harves

I'll give you AN opinion, just to get things rolling.
I'd say you started flushing too soon!
She's a pretty plant, just looks to be fading early. I'd give her at least a week & see if more pistols showed. If so, wait for those to turn, if not times up!

If they are all milky and a few amber then usually i would say its ready but looking at your pic it still seems to be filling out.. How long into flower from first signs are you?

It maybe wants a few more days to a week, i would monitor trichs to make sure your not loosing strength and leave it a little longer. if you see more and more amber trichs chop her down as this is thc degrading and your crop is loosing potency.

Happy Growing

You got a couple more weeks ,
By the look of your pistils (white & erect) she is still putting on weight .
Check trichome heads on the bud its self not on a leaf , the leafs will ripen faster
