Calcium deficiency use calcium magnesium. Could be boron but that usually has twisted leaves and starts at the tips and is rare

brown spots sugar leavesI've asked this before, but the issue still seems to be there though it's very minor. Some of my more developed buds sugar leaves are showing brown markings. Last watering I flushed her but the markings seem to be spreading still, although very slowly. What am I dealing with?

Calcium deficiencyI already had a question a week ago, now it's easier to see, camera still bad.
But here are some fan leaves which I believe are showing a calcium deficiency.
Calmag is in the post, just waiting for it.
Is it for sure a calcium deficiency only? Thoughts?

Mancha en hojaA que se debe que estén así algunas hojas? Es deficiencia o exceso? Regaba con 1000 ppm pero vi algunas puntas quemadas y color verde oscuro en las hojas así que lo fui bajando poco a poco hasta llegar a 500 ppm, y hoy note esas manchas(el agua drenada da 750 ppm)(coco y perlita)

Burn, deficiency or other?I’m completely stumped as to why my one plant is showing signs of deficiency or burn. Used the exact amount of fertilizer per plant. One plant is fine and the other looks terrible. I used a half dose of cal mag and it seems to have stopped but is not drinking or looking better.

Possible manganese deficiency?I fixed some previous issues and have not been feeding my plants. They are in peat and worm castings and pearlite. About 6.6ph soil, watering with 6.5-6.6 water. I am going to water with nutrients again to see if that helps just want to hear another opinion.
