Air flow/exchange is always great! Not too necessary when you have a seedling if you have a decent amount of space but never bad :thumbsup:

And as for nutes - I would wait until 3 or 4th week. Or even until you begin to flower (find out what you're comfortable with) And make sure you don't over nuteeee... dilute whatever you are using and gradually go up to the dose recommended on the label.
