The version u have is the original though. The real deal only is available in clone form. The one I grow is the real deal sky but is crossed with og 18 by reserva privida. But mine show the good pheno with three leaf with one curled looks like yodas fingers lol.
Mine stretches though and doesn't have really a main cola but it grows solid nugs which hold weight well most of mine are a eight to 5 grams or so dried.
things look pretty good.. kinda looks like overnuted or ph issue with that afghan.. but keep at it.. things keep getting better the more u research read.. and trial an error makes it easier every time... nice stuff tho.. good luck with everything.
