Autoflowering Roadrunner #2 - 18 days

Hey, i am new to growing and i've got a Dinafem Roadrunner#2 autoflowering plant under an 80w gro-lux fluorescent tube. (just an experimental grow before i buy a hps light) im into the third week now, the plant is around 6" tall and already smells skunky also there is white hairs on the top of the plant and by the look of it the start of a bud. Is this early or normal for an autoflower?
Ill try and upload some pictures tomorrow. Oh and btw has anyone grown roadrunner or heard reviews for it as i havent heard of it before.
Cheers.

I WILL DIG UP A PIC OF WHAT IT WILL LOOK LIKE AT HARVEST. BUT THE YEILD OF THE PLANT IN PIC WILL BE 3X BIGGER THEN YOURS. INLESS YOU INCREASE LIGHT GET 42 WATT CFL 2700K-3000K TRUST ME AUTO'S ARE MY SPEACALTY. AN HPS WILL DO WONDERS AS YOU WILL SEE IN PIC.. ALSO NO LESS THEN 20 HOURS OF LIGHT A DAY. IF YOU HAVENT TRANSPLANTED IN FINAL CONTAINER DO SO SHORTLY 3 GALLON IS IDEAL.WHEN DONE RIGHT THEY AVERAGE 3/4-1 OUNCE PER PLANT. BUT WITH CFL AND FLORO TUBES EXPECT 1/4-1/2 OUNCE:thumbsup:

ok dinafem roadrunner #1 first pic and a #2 second pic . if i remeber they were taken before harvest. good luck:thumbsup:
