Not sure why but I'm guessing your pH was a little high 2 weeks before this. Ok did I bingo?

sure ill play along, this looks like too much nitrogen at some point or this plant is a very picky eater, either way less nitrogen

White snipes on leaves... [ MAYBE THRIPS? SHOULD I USE POTASIUM SOAP? ]
Hey guys! Do you think these are thrips? The leaves have these white snipes already since some days ago. Also, If you look carefully, there are micro white things on some parts in the leaves that could be the thrips themselves. I'm thinking of adding potasium soap for this.

What is happening? (First Grow)
Is what I'm currently seeing nutrient burn due to low pH? If so, what can I do to fix a consistently low runoff pH (7.1 in 5.6 out)?

I'm still guessing what caused the disease i noticed on a single plant the first weeks of grow. A disease that didn't spreaded at all, and that affected only 2 leaves. You can see it on (Week 2 - Photo 21), (Week 3 - Photos 7, 11 & 17) & (Week 4 - Photo 4).

Anyone know what’s wrong with my plant? Has had marble Colour effect on the leaves since it was a seedling and is now wilting. I’m debating if I should remove it if it won’t flower properly. To allow the other plants more room to grow as this is only a 750x750mm tent with 4 autos

Calcium issues?
Is this the start of a calcium deficiency? Aside from these couple of spots the plant looks healthy, but I really don't want this to progress. I can't measure my PH for a couple of days, sadly, until I get the equip through the post to do so.

Is this nitrogen deficiency? Should I change the soil?
Is this nitrogen deficiency? I've been feeding them and using pH Down but nothing changes (pH 7.2). Should I replace the soil? They're in CannaTerra mixed with Promix. I've got some FoxFarm Ocean I could move them to.
