I started my two plants on 17 feb and my northern lights autoflower started flowering on 8 apr. My mystery plant just keeps growing so I went from 18/6 to 12/12 as per someone here advised thinking it might not be a autoflower back on 16apr. This morning I checked again and no sign of flowering after 16 days of 12/12 lighting. My question for you is do I toss it in the trash or keep it ?.
