Yellowing leaves... First grow...Help!

[PerachYarok]

Hi friends. First let me say how much I appreciate all of the help and camaraderie of this community. Really appreciate it.

Here's the short version:
3x3
Tsw 2000 led
Mephisto seeds
First grow
3gl smartpots
"Nature's living soil autoflower amendment" mixed with bottom third + happy frog

**I have only watered. I have never added nutes, other than adding a little cal mag 2 waterings ago.
------

It was way too hot at the beginning, so I had some real stunting and nitrogen burn. At the advice of the nature's living soil guy I flushed each pot with 9 gal of water about 2 and 1/2 weeks ago. Things definitely got better, but I've been dealing with some yellowing.

I tried folliar spraying with a little cal mag and some B-52, and I'm not sure if it made any difference or not.

however, in the last few days I've started seeing some significant yellowing on the lower leaves of these plants.

I'd love any advice that you all have. I've got another day or two until my next watering, and I have all sorts of chemicals here and ready for the next grow.

I am not a big fan of stratifying soil. I sounds like you rinsed all of the good stuff right out of the pots with the big flush?

First things first. What is the PH in the root zone? I would treat this as a regular soil grow and fertigate with balanced nutrients along with adding Mykos or other beneficial organisms. What brand of nutrients do you have available? Follow their chart for the stage of growth for your plants.
