When to start using ferts?

It's been about two weeks since I planted them, and on one I'm noticing a slight yellowing on the tips of the leaves on one of them...it looks like lack of nitrogen, but it doesn't seem likely to me that this would be happening this early..can someone enlighten me?:stoned:

some plants want nutes sooner than others ive noticed, a slight yellow on the tips of the bottom leaves will indicate that nitrogen is needed soon, if you feel a bit iffy about giving them nutes i would give them less than 1/4 strength nitrogen just to see what they do.

Here's an update...the two biggest ones have been given a bit of nutrients, but not much at all due to me being very weary of harming them, but growth is going somewhat well..I've got the reflection set up like I want it and I think it'll give me the most out of my light. :thumbsup: :stoned:
