Looks too young to show a deficiency, are you over watering? The roots need to get somewhat dry to breathe some too. What are you using for ur soil medium? One of the most common mistakes of newer growers is to think they are being a good parent by giving em lots and lots of water, but everything should be in moderation. If you are using a soil with alot of water retention the top may seem dry but they may be flooded underneath. If so, adding perlite may help with this.
Hardpacked soil will make breathing harder too, you want a nice fluffy, airy mix. I water mine with a good drench than wait several days before I do again, of course not waiting too long so they get wilted.

Yeah, you are overwatering.

Young plants are especially trying to grow their root system and they HATE muddy soil. They actually like the soil more on the dry side if anything.

Just water whenever they need it, it does not need to be on a schedule. Stick your finger down an inch to an inch and a half and if it is DRY then water. You want the soil to be moist but NEVER wet and muddy.
