Time of harvest/feeding schedule

Hi there,here’s my rule of thumb for harvesting 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.If trichomes are mostly milky/cloudy about 80/90 % and fill with some amber colour, it’s the time to harvest.Flushing or not flushing is your choice.So I would start using Overdrive for 2weeks when I firstly sighted amber trichomes on buds and then flush for about one or two weeks until I get my desired trichomes colour.Happy growing... ✌️
