I've encountered some strange behavior from a few plants. They seem to be growing straight up, without any secondary branches. The flower chutes come directly from the main stem. The flowers are very spaced apart. The clones came from the same mother as other plants that turned out normal (i'm 95% sure of this). It's not stretching; it was grown under a 1kw lamp. I've included some pics. Any suggestions to why this happened is appreciated.

It may not look that bad, but i assure you, it's absolutely unacceptable.

I'm not real sure what that is man, but recently in Late January i took some clones from a friend of mine and the first new shoots after the roots started forming were normal 5 bladed leaves... i feel like i might have put them under too strong of light too early or had heat stress but it went from 5 bladed leaves to a single bladed leaf like you have and they edges were almost cupped underneath, not the tip... so if you cut the leaf off and turned it over it looked like a canoe... after a few more sets of nodes the leaves went back to their normal shape... still not sure what it was! goodluck growing... and that bud still looks smokeable to me!
