Living soil. All organic amendments. 2nd grow in this soil. Week 6 of flower. Had the same issue with the last grow but not as bad as this one is becoming. My first thought is too many nutrients. However, the yellowing suggests to me that there’s a deficiency. Most likely phosphorus from what I’ve researched.

Also, from what you can’t see in the photos, a few leaves at the bottom of the canopy have had the same issue. The middle of the canopy is totally fine.

Just turn your lights output down 10-20%
They were pulling mag and that ended up spurring light stress.
What is your height set at?

I think you nailed it. Thank you. Running an AC Infinity Ionboard S24 in a 2x4. I was running at 100% power, about 18" above canopy.

Def cooking them homie! 80% most likely be a good place to start from here. 👊🏻🤡
Maybe raise the light 6-10 as well.
