Fastbuds girlscout cookies and lsd25 that emerged from soil Sunday evening. They are in happy frog soil. 12 plants under 8 23w 6500k CFL. Not sure if this is stretch, or just how tall they should be at this stage, as this is my first grow. Tallest one is about 2 3/8". They are 4 days old and some are getting their second set of true leaves. Should I move the lights up, or wait? Any advice would be appreciated. Thanks.
