hi there. my babies are about 6 weeks old, after looking at some pictures i believe my baies are leggy. by leggy i mean the stem is long and thin. plant looks a little stretchy.
That generally means they're receiving insufficient light, but I've no idea on your setup. How many plants? What are you using for lighting? How close are the lights?
It could easily be the lights. What type of lights are you useing? If your useing florescents then you can put them as close to an inch away from your babys without them burning the leaves. Also if you dont have a fan blowing on them it will cause the main stem to sometimes be flimsy. A light breeze on your seedlings promotes a thicker main stalk instead of a streched out one. Peace out.
