Put those babies in some bigger containers, and they'll thank you for it. That's actually a lot of nice root growth for that young of a plant. Go ahead and grab some 1 gallon pots and switch those ladies out. Trust me, you'll be watering less My from-seed plants go to three different homes over their lifecycle. Some ppl do even more though!

Bozo, I disagree about cutting off the dead tip. The pic doesn't even show us what the problem is (maybe work on your focus, Killa ) and until we find out, don't cut anything off. Necrosis should not occur in a plant that young. I'm betting it's a pH issue, but we'll see.
