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

Discolouration on fan leaves
Getting a white discolouration on my fan leaves. Thought it was residue from watering with nutrients as sometimes water will land on the leaves. But it doesn’t rub off, some parts look like it’s scratched into the leaf, some parts look almost bleached. But also considering PM?

Spots on leaves, brown shimmering.
I've read that it's a boron deficiency, but I'd rather be sure.

Calcium deficiency?
So, 2 out of 6 are showing this, it looks like a nutrient deficiency, Calcium I'd say. It's only present in one leaf on each plant, in the bottom. I've got here CalMag ready to apply, just wondering if you guys agree with me :D Thank you, and keep it green :D

Strange splotchiness has recently showed up in a few of my plants in different parts of the garden. I was thinking maybe CalMag deficiency? But I wanted to get an expert opinion. See latest photos.

Help the rookie w/ a possible calmag deficiency?
Does this look like a calmag deficiency? Link to my journal entry for settings/water param/etc for these to see if you can spot the issue? https://growdiaries.woodroom.tel/diaries/187101-grow-journal-by-mrlahey. Using TDS 0-2 ppm ro/di water with calmag additive.

Wilting leaves and copper spots? Save Me!
These copper spots started appearing around 2021-01-28, and the wilting leaves started 2021-01-29. The newest additions to the environment were the much stronger MarsHydro 300w light. I've had to water more often because it dries out pretty quick with the rampant heat. what next?

Mottling shiny spots in leaves/ nitrogen claw
What is the cause of the mottling on these leaves is it some sort of toxicity? Please look at my last diary entry (week 4) for info on recent feeding.

How do you harvest in hydro (drip system with a tank) when some are late ?
Half of the plants are late (chlorosis, iron toxicity, nitrogen overfd) on a scrog net. As individual flush is impossible, I guess I have no choice than having different batches of ambered trichomes ! And I thought about different strains next time, sweet dreams...

Am I correct in diagnosing this as Calcium deficiency in the Black Sugar? I gave a basic compost tea yesterday. What else can I do to ensure she makes it through harvest?

Brown/rust spots have been increasing on one of my 3 plants. Appearing on upper and lower, newer and older leaves. Does not appear to be a light/heat issue. Treating it as possible Cal def by increasing cal-mag nutes.

Brown Leaf Spots help!
I have a serious problem with two of my girls and I can't figure out whats wrong. The pics attached show the brown spots that have now spread to a good 60% of the leaves on each plant. I've defoliated as much of it as I can and its now affecting even the sugar leaves. Any ideas?
