Hello, i have a problem with my staurogyne repens, yellowing and hole on the leaves, then melt. I check the stem so far so good, so it happens only to the leaves. My tanks is 20 gallon, I dose EI , water change 50% every sunday, CO2 35ppm , 60 Watt LED Light DIY. Maybe someone knew this kind of deficiencies ? Here's the picture.

In my experience, when I see necrosis on the leaves, I think it’s calcium dificiency. I would dose 1 tsp CaSO4 per 10g just once. Then wait two weeks. You will see the improvement. Don’t forget to continue with your other dosages.
