Hallo! The BB All Mix is known for being heavy handed on the fertilizer side, with higher ECs. With what you're inputting cross-referenced with the images, the only issue I can imagine would be some sort of lockout phenomenon. I would dig into the runoff numbers, perhaps add a flushing agent for a one-off mini-flush, and look at it as a soft-reset on my medium as soon as I could. 👽

At first glance you see the rust colors and spots which would say calcium but then looking further at the yellow stripes it says magnesium too. Hate to be the “just give it some calmag” person lol. But yeah.. Seems to me like the 0.6 calmag isn’t getting it and needs to be increased.

my wager is on lockout. Ca and maybe K being inhibited. in soilless this is just a formula adjustment, but with soil, you may want to dilute the substrate a bit and re-formulate going forward. trial and error until it's smooth sailing seed to harvest.

I also think it looks like a calcium deficiency. Brown or rust-colored spots on the leaves, especially on the new growth near the tips of the plant, are a sign that it's calcium. Increase your dosage. I give 1.5 ml per 2 liters of water with each watering. So every 3 days more or less. Good luck!
