1st grow nutrient issue or?

1st grow autoflower, is this a nutrient issue, septoria or something else? Fox farms happy frog soil, 1/2 dose of big bloom and tiger bloom. Ph is fine. Watering with rainwater because our well water is super alkaline.

Could be fungi. The marginal necrosis makes me think too much salt. And the leaves with lesions are not widespread on the plant.

What is the pH of your rainwater?

I'm wondering about the transpiration rate. A high rate can reduce the amount of water and nutrients that reaches the extremities of the leaves.

What are the temperature and humidity?

Yup.

Ahh - I think that’s it. We’ve been struggling to keep humidity up. Currently 74 degrees and 43% humidity but it has fluctuated quite a bit. I thought keeping it watered would avoid any problems but that makes sense.
Thanks!
