It is the end of 9th week (5th of flowering) and the hairs are becoming curled and brown. Now, I cannot see if thricomes are milky because I have no microscope so my question is: how can I understand when to flush the plants? Is it now the right time or should I wait a week more?
They are not ready just yet. Flowering can take anywhere from 6-12 weeks. A good rule of thumb is to wait until most of the white pistils have turned an amber color or curled. However this is NOT the most reliable and effective way to judge harvest time. I would recommend going onto amazon.com and buying a jewelers loupe. They cost around $10-$15 and can help you see the tricomes on the plants leaves and bud. When either all the hairs have turned reddish in color or half of the tricomes have clouded than go ahead and flush out the growing medium for no less than 7 days or until most of the fan leaves have yellowed. Good luck on your grow. I will check on in if you have any other questions.
Buds are thickening but i’m not sure if starting to flush or continue to fertilise, maybe I should continue to fertilise just a few days more and then flush. Any advice?
