First time grower and noticed this with my leaves. Was thinking Nitrogen deficiency but not sure. This baby is 4 weeks old today. Can anyone help.

Welcome to our happy place. Are you checking the PH ? Keep it between 6-7. I can't really see for sure, but it might be time to replant to bigger pots.
 
I was having an issue with ph. My tap water is pretty high amount 7.8 and I just changed to distilled. I ordered ph up and down and a new tester just to be sure. I am repotting them this weekend into five gallon smart pots.
 
Thank you both so much. Should I be giving them extra nutrients at this point.

No, be careful with nutes when they this young. If you are transplanting this weekend. Just give them PHed water, (very important) for about a week then start giving them nutes at half strength off what is recommended. This is the period in your grow when you can screw up very easily. Once you get them established in their permanent pot you are pretty much good to go. Good luck my friend.

I have had issues with PH meters. I've had trouble with it reading true. Always having to keep the probe wet. Now I use litmus paper. Just dip it in the water and compare color. You don't have to be exact, just between 6-7. K I S S
 
That looks like a deficiency but I don't think it's nitrogen (which makes lower leaves turn pale yellow all over). The pH being too high or too low near the roots in the number one reason growers see nutrient deficiencies, so that's always the first question everyone asks when they see a deficiency :)

If in soil you want to pH to be between 6-7, and in coco coir you want to keep the pH between 5.5-6.5.

Here's how to test the pH

What type of nutrients do you have and what type of water are you using? In coco you need to start using nutrients right away (since there aren't any nutrients in coco coir) but in soil many growers wait until the plant is a few weeks old so it has a chance to use up some of the nutrients in the soil :) They also look a little big for their pots, maybe time for transplant?

Overall your plants look great!
 
I have tested the runoff water now using distilled and it is in perfect range. I'm going to the indoor hydro store tomorrow to get some more soil so I can repot them into a larger smart pot. it is nice to hear that they look good. I was never a great gardener. I killed my eucalyptus after 2 weeks. lol. they didn't have a chance. thank you all again though.
 
Yes I saw you are potting up, good timing. Post a pic of the root ball if you have time. I would be very interested to see it. I attached the link to Nebulas transplant guide.
