stop growth

Hello everyone I have a seedling about 3 in big 9 days old appeared to stop growing and white lines and a couple spots on the leaves can anyone tell me what I did wrong before my next attempt gonna let it sit for a few more days to c what happens. This was my 1st attempt im practicing on bag seeds using cfl's 2400 lumans total I was thinking maybe more light. Any advice?

At 9 days I don't know how you can tell that they quit growing. It takes about 14 days for them to set up a root system, than they will grow from their. The CFL'S are going to take a lot more time to start growing than led or hps. Just give it some time.
