You are quite welcome!
I will put it in the corner of my flower room and switch it on for 6hrs during the 12 light.
To see the best results, use it for the same 12 hours
Have you tried adding a UVB or do you just stick with the multi spec MH?
MH has uvb light. (not as much as a light made for UVB) I have started using HPS now too in th mid-late stages of flowering. I still run MH the whole grow though. My origional goal way plant potiency, now I am moving to up yeild with no degrogation of quality. I am filming the whole process and hope to produce a growing DVD set.
Any suggestions on how I deal with the purple?
I have barely used nutes on the grow at all. My last watering I gave them about one third recommended of Ionic Grow,
That is part of the problem. Give them recomended amounts. I know you don't want to burn them, but don't starve them by doing it. Put a drop of non-antibactrial dish soap in every gallon you feed them. This will help with soil penetration and also help get more o2 to your roots.
Between the 24 hour days and the under feeding, watch close in flowing for hermies. You plant is a bit stressed out. Your expecting a lot from her and not giving her the tools she needs to get the job done.
