Organic soil recipe experiment for autoflowers

I have been working to tailor a soil recipe from locally sourced ingredients that will carry my autos from start to finish. There are so many variables when working with autos it's been a challenge. But I think I'm close with this specific cultivator. Currently on day 52 from germination. This is the start of its second week of flower. Water only phed to 6.5-6.8. appreciate and feedback and or suggestions.

Looks beautiful
