Second grow

Im on my second grow got about 12 so far but a couple r stretched and week stocks. is there any thing i can do to strengthen them.
bagseed
3 23wcfls and 2ft 17w flo
no nutes yet
2nd week about 6in tall
mg moistercontroll ps

put tha light closer about 1 or 2 inches away

got light closer but they r already week stem and BIG leaves weighing them over

get some more air flow on them. a little breeze blowing on the stems should strengthen them up a bit.

will try that thanks
