I have a problem with yellowing leaves. Yellowing appears immediately after germination. And it continues until harvest. I thought it was the fertilizers. Fertilizers that are old. I threw away the old fertilizers and bought new ones. But the problem still persists.

I have the light at a height of about 40 cm. The photo is taken immediately after watering. The water drains as it should. I use biobiz lite mix. I think it will be poor water quality or spoiled fertilizer. How do you recognize spoiled fertilizer?
