Nitro def? Need help ASAP

Woke up this morning and checked on the babies, this one hawaiian snow looks like crap the bottom old growth including the cotyledons are yellow, from what I've seen online so far is that it is a nitrogen def, I'm using roots organic soil mix with general organics go box if that helps, please help don't want her to die

It does look like a nitrogen deficiency. How old is she? And how often do you water her?

pic of whole plant might help.

Around a month old since the lights been on, and the thing is I've been dealing with fungus gnats using sns 203 and azamax, so I let the soil dry out pretty good each time but their in one gallon pots so like every other day usually is an average.

time for a pot upgrade.

That's what I was just thinking? Needs transplant? There at that time was gonna do it this morning till I saw this

Transplant to a 3 gallon pot or larger.
The starters and lowers (leaves) will die off as the plant grows "up".
Foliar feed a nice N based foliar a few times and continue on as you have.
If you do begin an N def later on down the road.....Add some fish emulsion for the high N twice (one a week for 2 weeks) and continue. Try not to get feed solution on the leaves and leave it there.

Whats the strain?

Looks nice so far.
