First time grow need advice

[Lemonginger]

Hey everyone, first time grower here. I’m currently running 3 purp lemonade autos from fast buds and they are right around 11 days old. I’m using a mix of fox farm happy frog and ocean forest in 5 gallon fabric pots. Still haven’t mixed anything in the soil just simply planted into the pot and kept everything moist. Everything has been going pretty well so far but when I got home from work today I noticed one of the plants is starting to show some signs of what I believe to be either a nutrient toxicity or overwatering. What do you guys think my issue could be? Any tips or advice would be appreciated.

The first two photos are of the plants showing signs of a problem. The other two are looking good in my opinion but please do let me know if you guys disagree. Thanks again!

top soil layer look rather dry to me, when was the last time you watered, how many days and what amount of water ?

also did you moist the whole soil till a little run off first watering after transplant ?

I'd be giving these at least 5oz slowly in a circle around outer edge of leaf.

What are the temperature and humidity?

I haven’t transplanted, simply planted into the 5 gallon pots. I did not water until runoff at first, is that something I should have done? I’ve been giving about 4 oz of water every 3-4 days. I’ve also been coming in pretty much everyday to just lightly mist the top of soil to keep everything moist.

Am I not watering enough? Should I water until runoff to get the entire pot moist or stick with 4-6 oz around the stem for now?

My temps have been around 76-82 with lights on and 69-72 off. Humidity had been my weak link it’s been around 45-50. Humidifier is coming just waiting for it to get here. Thanks for all the info and advice!
