I'm not familiar with the canna a/b, but IMO if you have a true 250w HPS at 12 inches them
being that small probably a little light burn place you hand over them about 2 inches above
them and see if you feel the heat from the light, if you do its to close...

Are you feeding daily to substantial run off?
Do you give plain water?
What is your pH going in?
Do you let it dry out?

originally I wasn't doing run off daily because the pot it was in is massive
no plain water
ph of 6
and no drying out
