Thanks for the reply.

I think you might be right with the watering.
How often should these be watered? (i.e. every 3 days, once a week?)
There are two "purps" that are hurting. Stem doesn't look like it's getting thick and kinda looks weak to me compared to the others.
Also they don't suck up as water as the others do. Any suggestions?

Questions:
1. How often should these be watered?
2. Is is a lost cause for those two?
3. How tall should they be to twitch from 18/6 to 12/12?
