Yellow leaves and yellow circle on leaf

i shoulda said at top of last message after first paragraph -- you'll be fine.. as the plant matures it won't be a further issue 99% of time. it'll correct itself. do read about the irrigation habits if they differ from yours, though. if you do wait for top 1" to irrigate and get a little runoff, you can skill the 2nd portion of that answer.

The spot i wouldn't worry about. Those first 1-2-3 sets of leaves can be funky and nothing is wrong with plant. The burnt tips is possibly because the soil was too "hot" (little too much nutrient content in it). Irrigation habits could be part of it too. If you are trying to give it a set amount of water per day or choosing the volume, this is not a good practice. If you think the pots are too big for the plant yet, you water a circle around it, but you make sure that column of moisture gets all the way down to the bottom, no matter how much water it takes... or, when plant fits pot, water entirety of pot all the way down.. In soil you'll want just a minimal runoff to make sure it was enough. If you water at same dry-weight, it'll take same volume to irrigate it. This is how you can better predict how much water you need -- more important when you are mixing fertilizer so you don't have excess sitting around for many days. You may get a little excess runoff the first cycle, but after that you'll more accurately predict volume as long as you do so at same dry-weight of pot -- top 1" dries give or take, lift pot to be familiar with dry-weight. That's your trigger to irrigate and irrigate fully. if you don't do this, the roots will grow in higher proportions superficially.. they won't dig as deep. you'll have a dry back around edge of wet/dry portions of substrate that could potentiall lead to high doses of nutrients in that zone. each time it dries off the nutes will not evaporate with the water.. they stay there.. then you add more fertilzier and that dries back and more deposits alongn edge... and so on.. this can cause major problems later on the longer it goes on. best for plants to fit the size of the pot, but carefully waterring in a diameter around the plant and short of edge of pot is fine too. do make sure that moisture goes down, so roots drive down.
