Training stopped and allowed them to grow through the screen now. Ec up to 1.1 but closest plant to window side in room still showing some signs of a zinc def. I think it may be due to training stress or cold sided corner. Hopefully now training has stopped it will start to recover more. Will also try to keep that side of the room at a higher temperature. Just hanging back and hoping the stretch goes well and they finish up quite level and about 12-15” above the screen. Thanks
