Today I transplanted my plant. Different soil, starting soil mix with root growth nutrients mixed with pear lite. I accidentally tore a few roots but nothing major. 8 hour later i see this spot. rest of leaf is fine and rest of leaves are fine (except the bottom leaves that are yellow and curled at tips). The soil ph is 6 at the bottom and 7 at the top. It cant be nutrient burn cuz it doesnt have any hardly in it, and its no where else on the plant.

Can anyone tell me what this spot is from and what should i do to fix it?

BLACK DOTS ARE DIRT FROM TRANSPLANT NOT BUGS!
