Hi I'm Karizma. I have a DWC set up with four plants spread between two containers. They are both being treated with an air stone and receive fresh nutrients every 3-4 days, or as needed. I am using GH products for nutes and lime as pH down. They have been in flowering for 3 weeks now and I am wondering when I should stop giving nutrients. I have removed most of the fan leaves to encourage more growth at the flower sites. I would appreciate feedback on what to look for to know when it is time to flush. Thanks
