Septoria, deficiency, neither, I don’t know?

Is it possible that it’s solely or possibly mostly a light issue and not a deficiency? It’s the worst on the tallest plant, which is therefore receiving the least amount of light at the depth of the yellowing.

Also last night I gave them their first only bloom nutes at a slightly higher ppm than ever other feeding they’ve gotten, though still only 615ppm. A touch of silica as well. Noticed a fair number of tiny little yellow spots that have developed.

Some before and after tonight’s horrible job..

If I ever have 80 or so tops in this tent again, and I damn sure hope I never do, I will definitely get a screen in sooner..

Slowly but sure I managed only one top per square!

If you guys were me, would you prioritize lollipopping or some fan leaf defoliation next?

Kinda feel like I should get some airflow under the canopy sooner than later but maybe I’m okay for another week, I don’t know.

I was planning on putting a 6” oscillating fan underneath the canopy but the pots and plants are too big. There’s really no room.

I’m thinking airflow under there is pretty important yeah? Since I can’t get any fans under there, I’m kinda thinking I should pretty heavily defoliate and of course lollipop. That way, the breeze from the two above canopy oscillators will have a better chance of moving some air down below.

Seems necessary to remove most of the large fan leaves to make that happen?
