pls kindly advise if these white spots are mold on soil? I am new to planting mint indoors. Thank you.
I'm not sure your seeds will ever germinate in that pot - the soil is saturated and fungal activity is almost a given in such circumstances. If you have any seeds left,sow some in an ordinary pot or seed tray with drainage holes, into new, damp potting (preferably seed starting) soil. Water carefully as necessary, but don't let the soil get soaked, allow excess water to drain away. If its still cold where you are, they may need some heat to get them growing, but otherwise, just stand them on the windowsill, but not in direct sun all day. Once they start into growth, wait till each seedling has at least one set of true leaves (the first leaves aren't true leaves), then carefully prick them out into individual pots around 5cm in size (bigger than that little pot you've got there).
