Well the only reason its growing so slow is I started it off in the soil and didn't move it into a system until about week 2 so in reality its only been in the system for a week. The stretching I imagine is from my light which i have 2 one is 75 watts fluorescent and the other is 75 watts again I had the main light above the plant about 6inches away...soo...the stretching I'm not sure how it happened...will stretching come into affect later on??
