Burmeseanswered grow question 3 years ago Hi there, Check the trichomes colour on buds(calyx) not on sugar leaves and here’s my rule of thumb for harvesting or flushing period.During that time,the leaves will show deficiencies, yellowing and most of the white pistils become orange.The best method is using 60x microscope and check trichomes colour on buds.If trichomes are mostly milky/cloudy about 80/90 % and fill with some amber colour, it’s the time to harvest.Happy growing... ✌️
