Odd color in inner leaf help

UnrealTairostarted grow question 6y ago
Day 10 I noticed the leafs around the edges are all nice & green but in the inner parts of each leaf it's looking a bit rusted, more so just grey after examining the photos. Is this a deficiency? Fungus? I've adjusted the PH to 5.7 temporarily
