When to begin adding nutes?

[michaelpeg]

usually seedlings don't need nutes for around 11-14 days, or when you have 3 alternating internodes @ 1/4 strength.

3 alternating nodes, wouldn't that be a little late? I usually dont have alternating nodes for over a month.

I have always had to feed my plants around 5 days otherwise they wont grow at all in soilless mixes. in foxfarm, i'd say 2 weeks but I have done only 1 grow with it and was not impressed for $50 a small bag.
