Looks a little better, but it still looks like it wants some love. What type of soil are you using, and do you know the pH?
Maybe try watering from the top. You can always test the runoff for an approximation. Even if you use a cheap pH test kit.This soil man. And I'm feeding just water from the bottom. Making the roots work for the water. And can't get a pH tester until the covid-19 is over. View attachment 4522645
My guess would be your soil. It looks like it has time release fertilizer in it that can jack shit up. I don't know anything about that soil personally.
If you want cheap, Walmart has 1 dollar bags of just soil I would a perlite to it because has next to nothing in it. But the soil works fine. I have had to use it since covid 19 because nothing is open.Probably
