Rust?

I was gifted this auto seed from a friend.it has had major leaf defects since it was a seedling. But it's growing well enough to leave be. But recently it started to get some spots on the leaves.

I keep it at 75°f 45-50%rh with a 300w led 22 inches above

What is the pH and PPM of the soil runoff?

@Mr. Grow It no idea. I don't have anything to test with at the moment....

@edwardilles25 Without the PPM measurement, we are just guessing what the problem could be. It could be too low of PPM indicating it needs a feeding, or too high of PPM causing a nutrient lockout.

Without the pH measurement, we don’t know if the medium is in the acceptable range for nutrient uptake. If the pH in the medium is too high or too low, you could get nutrient lockout and see deficiencies.

@Mr. Grow It thanks I'll get a meter and test.

I'm also indoor and in soil. I've been feeding fox farm bloom and big bloom every other watering at 1/2 strength.
