Ok so I have all my plants in rockwool and hydroton rocks. they are 2 months old from seed and they are all under 1 foot tall. For some reason they are all so damn short with about 7 small 2-3 inch lower shoots each. I did train them and topped some but I don't understand why they are stunted so badly?!!?!!? Ph is about 5.8 temps have been very low though at nights temps sometimes get to 69 degrees in the basement... Light is 400 watt MH and 3 floros. Can anyone help me out???? What can I do to get some length growing on these babies.
