I wouldn't be too harsh on yourself, those AF were tore up from the floor up. Might not have even been your fault at all. Do yourself a favor and dont grow those Lowryders. I know you think I have an axe to grind with Nirvana, and maybe I do, but that stuff sucks. I suggest checking out Sannies, his seeds are outstanding. And, you can pick up one of his Breeder Choice seed packs for Thirty bucks. He charges five dollars for shipping. Thats cheaper than Nirvana and his genetics and breeding techniques are 100 times better.
But if you grow the Lowryders, then good luck and I hope they work out for you. Cryp.
