Seedling yellow green?? Help

You need to use more water!!! 1 liter per plant per day at the beginning.

Hi dude. Balance water with 6-7ph and add feeding water o2 like doing it for fish tank and keep o2 constantly for it. You will progress…

Hi man there's nothing at all to worry about here sometimes when the seed cap comes off abit earlier they can tend to be a lighter green but they are not your true leaves, so you have nothing to worry about your true leaves will grow in a few days

They round cotyledons are not true leaves, it is the serrated ones that will sprout from between the cotyledons that you need to watch. At this stage you have nothing to be worried about, give it a chance to develop further before stressing.......most probably they will green up in a day or so, once the chlorophyll gets going.

Shes more than likely just young and hasn't developed enough chlorophyll to give her the vibrant green color you're used to seeing. This will happen given time as she matures and photosynthesis takes place. This also happens sometimes when your medium is too moist but that also will be fine with time. Hope this helps.

ora dovrebbe essere gia a posto..la parte interna è gialla perche non ha ancora iniziato la fotosintesi appena ha luce si apre e i cotiledoni diventeranno verdi tranquillo

I think it's ok, I've had that before. You'll know it's ok when you get the first fan leaves. Maybe too damp when germinating? Just water very sparingly, like I would use an eye dropper with water in it to darken the soil around the seedling about 2 inches in diameter. Increase the water when you have about 3-4 rows of fan leaves.

Nothing wrong with it. Give it a couple days you will see. 👍
