This is my first grow. just one plant to try out. The plants growth is stunted, in the picture its probably a month old. the leaves are yellowing at the ends, and the lower leaves have died. I want to grow this plant hydroponicly, built an ebb and flow system but need some more information as to the water, what to put the plant in etc. so for now i have it in dirt to get it going. I dont know if thats what i should do or not. could someone help me out with this unhealthy plant?
