Leaves like crazy, but no height

This is my first CFL grow, so there are plenty of things I have left to learn, but a small problem has already begun.

My plants are developing a large number of leaves (all in pairs) but are not growing in height. I have not noticed any measurable height difference over the past week.

Setup:
Mylar'd 1'w1'dx4'h cabinet,
suspended CFLs, 2/plant currently, about 2" above plant tops
4" round airstone per bucket
1/4tsp of FloraGro per gallon

Is this normal for the plants to be developing out, but not up?

I will work on getting a pic up within a day or two to illustrate this situation, but until then....?

Probably an indica strain...they're characterized as short and bushy with fat leaves

maybe you should get some shoes you hippy!

if you want some stretch, pull the lights up.

I heard if you put the plant under 24/0 hours of light it will produce closer nodes (sets of leafs) and if you do 18/6 it will let the plant grow out a bit bigger then if it was left on 24/0, keep in mind that your plant will grow up to twice its hight when you go into flower
