Burmeseanswered grow question 3 years ago Hi there,hereβs 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, itβs the time to harvest or flush if you are growing inorganic.Happy growing... βοΈ
