Babies are almost 3 weeks old and looking very healthy and bushy. They are in 50% seed-starter soil 50% Supersoil, watered every 2-3 days (very dry here) with spring water. No ferts yet.

Lights are 3 each 13 watt LEDs (red and blue) and 3 each 24 watts of cool and warm CFLs.

They are in 1 quart pots and are about 6" tall and about 6" wide.

Two fans provide cooling and fresh air.

The two slightly shorter ones have some very pale (lime green) edges on the leaves, but are getting enough light. I rotate them twice a day to get even lighting. No wilting or curling.

Is this 'normal'? Is it time to start fertilizing or what?
