Looks like acid burn. Maybe a drop of nutrients hit the leaf?

DeficienciesHey guys,
First two pictures are from one plant and the third is from another.
Any idea what the issues are?
First two pics I’m thinking phosphorous? The markings are only in one section though.
Second I’m thinking cal mag?

Spotting issue consistent in all my grows. Have always thought Cal deficient but more Cal never fixes the issue. PH always checked with 2 PH pens 6.2-6.8.Always pops up around the same time in flower.. week 4/5. Brown irregular spots and occasional curling down on the fan leaves. The only things I have consistently used in all the grows is the LED light, RO water, and CALiMAGic. Switched to dry organics but now its back. N toxic?2 years ago

Cal-mag issue that won't go awayI keep getting a cal-mag deficiency. I have been using 1ml per liter of water - 4ml roughly per gallon. It is only 1 plant, the same which has had the same cal-mag issue since early veg.
I include cal-mag every watering and nutrient feed day.

Is this pH related?Hello, mates!
Anyone knows what this could be? Searching I found that it could be pH related. I use pH controller from ferts (pH perfect from advanced nutrients) since the beginning, so I think it's odd that it could be a pH issue.
p.s. 3.5 weeks of flowering
Thanks 🙏 🙏Leaves. Color - Dark-brown
