The Tips of My Leaves Are Turning Yellow?

Currently I have a plant that is in a couple of weeks of vegging and has three layers of nodes. The tips of the leaves at the bottom (which are the first set of leaves that were first there) are turning yellow. It is not the whole leaf but only the tips. A fan leaf has about five tips or points. Only two tips or points are yellow but the nodes in the mid and upper region are healthy and green. Overall the plant looks fine but I was wonder why only two tips on the fan leave are turning yellow?

Hydro or soil? What kind of lighting and where?

My assumption is that they are getting a little burned from the lights. Move your lights up a few inches.

if it is just the first set of leaves i would not worry too much, their job is to get the plant going, and are the first to die off once you get a few sets of leaves.

are you feeding nutes? if so not really necessary till 4 weeks into veg, then start on 1/4 strength and build up.

if you notice the yellowing progressing up the plant then alarm bells should ring, until then RELAX bro.

thank you for answering my questions. by the way i am a soil grower using cfls. the top leaves are fine but the bottom set tips are turning yellow. therefore i dont need to lower them cause the top leaves closer to the lights are fine. Also i am not using any nutes right now. but my plants are about 5 weeks old so i should use a nitrogen effiecient nute and then when i flower i should use a nute that has more phosphorus right? Anyway any good suggestions on what nutes i can get?
