Calcium deficiency.
Add cal/mag to your line up or increase the dosage if already using a cal/mag supplement.
Remember too, what is showing now in the leaves, is a direct reflection of what was happening in the root zone 2-3 weeks ago, meaning this issue has been manifesting for some time already.
Also, improvements will take 10 days or so to start showing up, it won't happen overnight!
But the sooner you start, the sooner you prevent the issue from becoming worse.
Damaged leaves will stay damaged unfortunately, but there is no reason to remove them just because they "look ugly".

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.

Leaves browning in multiple spots Lower leaves yellowing but have green veins.One plants leaves are browning in multiple locations. I attempted to diagnose the problem with runoff tests. pH was 6.5 and TDS was around 900ppm, which was expected since they received nutes that day. Despite not spreading to other nearby plants, could it be leaf septoria?

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)

Burned upper leaf edgesHi!
Dark spots appeared on some upper leaves overnight.
I don't think this is the cause, but I did a pretty heavy defoliation the day before.
the spots only affects leaf margins and makes the tips curl up. The spots are brown, burned and slightly purplish.
what could this be?
