After recently receiving seeds for planting and posting about it earlier, unfortunately, only 2 out of the mentioned 5 Critical AK58 (Automatic) seeds have sprouted so far, with the others yet to emerge. The ones that have sprouted seem to display some deficiency, as evident from the discolorations on the leaves in the attached image. I'm unable to pinpoint the cause of this issue. Perhaps someone here might have some insights to offer.

Currently, I'm only watering with plain water at regular intervals. The lamp is positioned approximately 60cm away from the plants, operating at the lowest light intensity. The soil I'm using is just standard organic soil from the hardware store.

Any advice or suggestions would be greatly appreciated
