when to harvest

Hey everyone...first time growing and im looking for a little advice, i have a plant that i grew from seed...(apparently it is called "emerald green wonder")i started in march, grew it inside and moved it outside when the weather was appropriate. The first day of flowering or first sight of hairs began july 20 and it has been flowering since. I have a scope and have been watching the colour of the trichomes but because it began so early or is july early?? would it be ready to harvest now?? "most" of the hairs are still a white-yellowish colour and some are amber

wait untill you see about 20-25% amber, and all the hairs have receeded down to the bud. it will just look done to the trained eye

Look at the trichs and not the hairs
