Can anyone help me diagnose what the problem with one of my girls might be ?

I watered them yesterday morning. One of them is seemingly fine, but she's flowering and it looks like she's going to be one big flower!

The other has multiple bud sites, but i've noticed that the tips of the leaves are drooping (see pics below).

I've recently changed to my red CFL but I don't understand why this isn't happening to the other plant. Nutes needed ? Something else ?

They're in 10l pots in JI #2 soil, they've been in that since the start. they're about 5 weeks old after poking through the soil. Any help is greatly appreciated!

Here's a pic of the drooping (the brown tip in the foreground is where it touched the light )



Here's a pic of them both together, you can see how much better Curly (on the right) looks, although she's a lot smaller and doesn't have the bud sites that Wurly does!
