What is the deficiency in these seedlings

They are in ff light warrior.
1gal pots straight from germination
its about 25 days since they came out the dirt.
they are growing so slow and in the past 10 days the lower leaves started dying.

I had a similiar problem but had bugs aswell, dont worry about growth just yet (the roots are doing there thing)

However some cal-mag would help your situation.

-dont stress

Thanks, I am using all the patience i have. I tell you this much. I will go from germination to solo cup the next time around instead of a 1 gallon smart pot

It has to be doing something different ...I know strains are different, but I do not germ, seed goes straight in soil, and I have before just put them in a 5 gal, they should be bigger then that with almost 4 weeks, even a sativa...bad genetics imo....maybe wait another week and pull if 0 growth

Here is an update on how they are coming along. stil growing slow but they are growing.

And the other baby. i welcome any and all constructive criticism. They are coming along slow. I am about to take them out of the light warrior in a week which I think one of my problems is and putting them in an ocean forrest 3 gal. I will dilute the ocean forrest with some perlite

Light Warrior is for seed germination and plants with low nutrient needs. This is one reason why it's good to start in a smaller container so you can transplant into something more nutrient-rich when they are ready for it.

Those plants look to be nitrogen deficient, but this could actually be exacerbated by underwatering. Soil surface looks really dry to me in all the pictures I have seen. Obviously I can't touch it or lift your pots, but there should always be moisture. Don't be afraid of overwatering especially in smart/fabric pots. Those will dry out real quick, especially once some roots have grown in.

Give us some more details about your set up though: lighting? temperature?

That was the first lesson that I learned. I shouldn't have skipped the smaller container.
they are each in a one gallon pot with 2 cfls surrounding each. all are 6400k about 50w surrounding each plant. The temps have been between 79 and 85f. i have one fan in there blowing from side to side. no exhaust yet. i have been watering them about once a week. I read so much about overwatering so maybe I let them get too dry too often. they have been fed twice. Once was about 1/2 strength of the recommended dosage for seedlings. The second feeding was 1/4 strength of the recommended dosage for veg. the ph of the water used was 6-6.5.
