Burmeseanswered grow question 3 years ago Hi there,I answered in your last question about when to use overdrive and here's my rule of thumb for harvesting period.During that time,the leaves will show deficiencies, discolouration ,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... ✌️
