Growing Nasturtiums from Seed

Eastlake, OH(Zone 5a)

I have 32, 4 inch pots of Nasturtiums growing in my basement under grow lights. I have read different advice about fertilizing them. Since they are seedlings, I was going to fertilize them 1/4 strength of fertilizer, I have have read reports not to fertilize as well as to fertilize Nasturtiums. Could you please advise me as what to do?

Smithtown, NY

I grew mine from seed and as soon aa the weather was decent they grew vigorously. No fertilizer.
