All the hairs will turn brown or reddish and the crystals will settle.
Then it's done.
White hairs means it's still growing.
Also you can harvest difference parts at different times.

how far away do these plants look from bein done

red/orange/brown hairs simply mean that the pistils are dying, But has little to do with bud readiness or trichome color. Remember that mostly clear/cloudy will give you an uplifting head high, but harvesting with mostly amber will give you a more couchlock high. Never exceed 80% amber however because THC will begin to degrade

You are at the good part now, they will get fatter by the day.

Are you giving them any type of supplement like Bloombastic?

just feeding with a two part dutchmaster no additives first grow in many years just wanted to keep the variables low ive never seen a tricome in its amber color will i be able to tell by just using a magnafine glass or by the naked eye i just dont want to fuck this one up kinda counting on it
