Burmeseanswered grow question 4 years ago Hey friend, It’s normal to show deficiencies when they are close to harvest.But I think it’s aliittle bit early to be like this and quickly spread to top leaves.For now,you would stay with your nute dosage and check trichomes colour.If you think buds are in one week away from desired trichome colour,start flushing soil. 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.That’s the best time for you to harvest.Always adjust your water pH around 6.5 whenever you water.Even for flushing.Happy growing...
