UpA few leaf tips slightly yellow!

[TheHabsburgJaw]

This plant is 20 days old since it popped from soil! The plant is really short, bushy and overall healthy. But I noticed on just a few of the leaves the tips are slightly yellow, like the one I circled. I've kept it easy on the nutes. Like I said not all the leaves are like this. Just a few .Any thoughts. I circled the yellow tip in pic!I think they look pretty green and healthy overall for 20 days old!

They look just fine but make sure you use cal/mag also.
