OK, I got a BC Bloombox and some Serious AK-47 seeds. I germinated the seeds and put them in rockwool under a clone dome. I have a few questions...

1. How long should I keep the dome on top of the tray?

2. When should I start giving them nutrients and not just ph balanced water?

3. Should I still have a warming pad underneath the tray?
(I don't anymore but when I did they seemed to like the humidity)

4. My sprouts are turning kind of a purple/red color, is this OK?

This is my first time growing and I would really appreciate some feedback.
