I could be wrong but in the first pic that leaf pointing to 10 oclock looks a little burnt. To me it just looks like overwatering. I do have some info for you regaurding plant size vs root size. Your plants roots should be the same size as your plant. So if your plant is about an inche bigger than you pot at that stage it may be time to transplant but you could wait a little longer. You want a nice compact root ball with out your plant becoming root bound. and when you transplant them to early the roots spread out because they have space, thus bypassing and wasting space that will be much needed later on.

IMHO your bigger plant can go a little bit longer before bing transplanted and that means the little ones could go even longer. Don't change them back now though, they're small so it's not a big deal, but I like to teach so now you know.

The other thing to is that plants don't like to always be wet, they grow very well with dry periods. A good judge of when to water is to stick your finger an inch into the soil. if it's still moist leave it alone, if it' dry then your ok the lower you go the more moisture so your plants are fine if just the top is dry, but this is a great time to water. Also pay attention to how heavy the pot feels because after a while you'll learn by the weight of the pot whether or not it needs watering.

Chin up buddy your plants should be better in a day or two.
