..thanks for helping guys!
...Bcn'- Red is spot-on about the light/roots! ...very small volume pots are a recipe for trouble, plus the unknown soil pH....just how small is it, what volume? It may be that the already dubious run-off test method wont' work very well here- -- due to lack of sample volume, skewing results,... You can still test the bag soil at least, and have some hint about possible pH issues,... I'd use at least 1/2gal, and then follow this guide--> https://www.autoflower.org/threads/...-for-run-off-testing-and-ph-estimation.41733/
... the damage on the lowest leaves is likely a defc., probably K,... could be unhappy roots syndrome too- or both! If top growth is okay, let it slide for now,.. as mentioned, those leaves typically are tapped out before too long anyway,...

The container is a 250ml container, and it's only about 3/4 full after water has pushed it down. I really hope I can at least keep this little girl alive to get any kind of yield off of her. Good news is the bottom leaves have held on and no further damage has occurred. Top growth is doing awesome! Definitely about to flower in a couple spots. If I get real close to said spots I can smell some dankness and that's got me pretty excited. I put some pics from day 20 up in my journal but I probably should have waited another day because it seems like it had a significant growth spurt overnight. I watered yesterday with just plain PHed water and she seems to have responded well.

Seriously, thank you all for the help! You guys are making this first round so much less stressful.
