Man they are sucking up the nutes and water like crazy. I have a water meter that I use to guage when to water etc..and at the moment they are getting 16oz of full strength Tiger Bloom twice a week Tuesday and Saturday along with their distilled water. I always water them with both some nuted water and distilled at the same time. I'm trying to decide now if I wanna take any cuttings or just wait and get new clones from the club later on. As I just got some Master Low x Lowryder and Skunk x Lowryders so I'm kinda full up at the moment besides tending my outside grow for this summer. Thats under a 400w HPS and FoxFarm Ocean soil...
