Should we worry about our seedlings? Amnezia and Gelato

We are growing 2 Amnezia and 2 Gelato in a 3x3 Vevosun tent. One of the Amnezia was planted 5 days before the others, because we overwatered our first few seedlings to die... and this is our 2nd try. The oldest one have sprouted about 2 weeks ago, the three others 1 and a half weeks old. They are all auto-flower, feminized, 100% germination seeds.

We have noticed the Amnezia leaves are yellowing, either from the center or the tip. Two days ago, we upped our PH a little bit because our PH was at 5.5 with the soil, now it's at 6.
Our light is Intertek (120V, LED19W) on the blue setting, about 20cm away from the tip of the highest plant.
The humidity is about 75% all the time, temperature at 23C and there is two fans, on lowest settings (one for the top of our tent and one for the plants).
Our soil is generic from the store, and we added slow release Nitro from Bud Juice (just a tiny bit because out pots are tiny).
We water with a spray bottle, just a little bit, twice a day (sometimes once), after letting the dirt dry up (the pots gets lighter and there is no humidity when I put my finger in it).

Do you think there is a problem with our two amnezia plants? We are thinking maybe it's just the strain's color? Thank you

The smallest Amnezia fell down today, I took it out of the soil and replanted it deeper so it would hold itself better...

I think im having the same problem

The PH sounds very low for soil, but the soil itself is probably to blame.

Are you using distilled water?

Looks like the soil is to wet to me and/or not evenly moist. If so, I would put them in nice, not to wet soil, very carefully. I’m not an expert but I’ve messed up a lot of seeds. Such small plants need pretty much no waterings and if the bottom of the roots is overwatered, such small plants will take a long time to fix it, If ever, from my experience.

These plants should be in flower by now if any survived. But the OP hasn't been online pretty much since they posted. So it's going to be much like how many licks it takes to get the center of a Tootsie Roll Tootsie Pop.

I hate it when that happens.

I grow with straight up tap water. Never had a problem. Did you add anything to the soil.or water in regards to nutrients? If not than they are too wet. If the last batch died from over watering that might be the same issue.

The tips of those seedlings will likely start getting crispy.

Once you stick a seedling in light those tiny wings should be up stretched in a V pattern.

Their dead jim ….

Issues when that small is tough
