I had a sprout that only had embryo leafs at first, also. Up untill about a month old, it looked like a mutant. It was growin abnormally and shit. Then it started to llok like it should, and ended up bein my biggest, best looking plant. Shame it turned out to be male. Its gonna stretch a lil bit more than the rest, cuz it doesnt have leafs, so its reachin to the light, to get as much as possible. I would get a drinking straw and some twist ties, or something cuz you are probably gonna have to support to stem, as the increased height will make it fall over. Other than that, you will be fine. It may have a better chance of bein male, tho, cuz of all the stress it is goin thru. This is all wisdom I learned from members of this site, so soak up everything you can from em, and read till your eyes bleed!
