Hello BigBud,
My 2cents, judging by your pictures. I'm being honest here, its what i see.
You dont have enough aeration, and drainage in your soil. Your soil's texture is too compact.
It isn't loose, light, and spongy enough,
This means there isn't enough room for your roots to easily grow, and spread.
This means plants grow "leggy", and your nodes look very stetched.
This means your soil doesn't dry fast enough, or drain adequately. Because of the lack of aeration rot can start. You have slouchy looking leaves, with downward curling margins.
My advice is to dry your soil right out. Also to consider transplanting into a more aerated mix. The plant is still small, you have time.
Test your soil's ph.
Best of luck mate,
Tim.
Edit: your new photos look as if the roots might have just enough aeration. They look happier.
You won't be able to water, or feed this soil very often. Keep it nice and dry, all the time. Also on the odd occasion you do water, give it a huge drink until ample runoff.
They may still grow leggy though.
Maybe it isn't 100% necessary to transplant after all.
Definitely aim for more aeration and drainage next time.
What is your current soil's ph?
