Hey everyone first post in a while been busy with my latest grow. Im growing trainwreck under a 250w hps in coco medium. I began flushing at the end of week 6 but now at the end of week 7 almost all the leaves are yellow just a few hints of green around the buds. Is it worth fertilising as I'm not 100% sure if theres one or 2 weeks left (gh seeds says 1 but who can really be sure) I dont want to miss out on the last 2 weeks of fattening up because of defeciancys whats the opinion on gc? No pics atm best i can do to describe. Leaves have gone from green to yellow over 2 days yellowing is on all fan leaves even those coming out of the buds. To fertilise or not to fertilise that is the question.
