k, well its been about a week. i do believe that i was dealing with nute burn, my plant has turned away from the yellowing collar although the leafs that were already affected havnt shown any further deterioration i dont believe they will ever get back to there "greeness" new growth is beginning to show at the nodes. here are some pics,

I am dealing with a little bit of purple in the stem/s. i think this may be due to the low temps here.

I have noticed that in the area where i bent the stem back and forth ( a few times a day) the area seems to have grown larger, Is this somthing that is practiced????? possibly to get stronger stems.
