No not calcium deficiency, but nitrogen toxicity.
You have burned leaves.
Calcium deficiency will initially present as small brow dots/spots.

dark inteveinal looks like a p-deficiency, but that should occur at bottom of the plant, first. (mobile nute)
P can be locked out by calcium. Have you added a ton of that over time? in a soilless/hydro context all you need is 100-130 ish.. local tap water will have some in it and causes a bit of variance as well is local VPD as far as what concentration you need of each nute, but it's a good ballpark for most people. if in soil, this info isn't too useful because there are so many unknowns about what came pre-charged in the soil in addition to your fertilization.
P also has a bidirection stimulative relationship with Mg.. if you added extra Mg lately but also didn't up dose of P with it, that too could cause a p-deficiency symptom.
Good thing is it is progressing fairly slowly? So, let it present itself a bit more to be certain. Reference a simply leaf chart and Mulder's Chart (informs about antagonistic vs stimulative relationships between nutes) to make an educated guess.. that's all we ever have.

Root rot or pH imbalance?This blueberry muffin (f) plant was doing well until last week when it started deteriorating. Its grown on a mix of cocopeat, vermicompost, perlite mix and fed on compost tea and cal-mag mix. I might put it down eventually but I checked the pH and it was 5!

Interveinal chlorosis and dead spots on leaves, deficiency?This started appearing about a week ago, after I watered until runoff with plain water. It's on a couple of leaves higher up both plants and seems to be progressing. I am feeding advanced nutrients Grow Micro and Bloom but have been using very low doses, like 1ml/L.

Too many nutes? but a couple days with water only and it's still getting worse. The other plant seems fine. The buds seem OK. Maybe heat? Soil is 69F. Overwater?

Calcium Deficiency???So this is a Calcium Deficiency right? Noticing on top leaves. Not bad yet but want to stop it before it starts as this grow has been my best so far. I have been using CalMag every water but I did lower the dose for a few days as I was told I was using too much for flower.

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Look At This Pigmentation!Lower fan leaf vs upper fan leaf in the canopy. The difference in pigmentation is wild! It almost looks like its bleeding.

Is that not enough calcium?How can I recognise that it is only a calcium deficide? The plant is also the largest and the only one with such deficiencies. Could the plant also be lacking manganese or magnesium and what can I use to compensate for this? Are pests or diseases excluded?

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled.
Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea.
Also, when should I start feeding the plants?
And how much water do I need at this point? 😥
