Many growers using LED need to feed their plants Cal-mag. It's just calcium and magnesium. Your plants look healthy so I wouldn't worry.

Calmag is probably one of the most commonly used products on the market. Usually contains a ratio of 4:1 or so of Ca to Mg. Mostly all Nitrogen based so you'll be adding N as well.
Usually dosed at 1ML - 5ML per gallon. Lots of variables dictate how much you need and if you need it at all. Most nutrient lines have some Ca and Mg in them, but nowadays in the LED age and prevalence of coco growers, most people have to augment it into their feeding routines.

Cal mag is the number one diagnosis for ugly leaves. If you start a thread now saying my leaves this..... like 10 people will say cal mag ... I’ve seen this happen my whole riu tenure lol
Other than that led users do tend to get the early fade more than hps nowadays ...

You have to watch though....sometimes having certain toxicities can lock out calcium or magnesium. I believe Boron and Nitrogen lock out Magnesium.

Also strain dependant. Ive had White Widows that were cal-mag hogs and I've grown Green Crack x Amnesia Haze where I barely used any cal-mag.

Excessive K can cause lockout(s) - common misdiagnosis for cal/mag, especially in coco.
Hit'em with the Hein! lol

Luckily (knock on wood ) I haven't dealt with bud rot yet. Fungus Gnats were fun though lol. Yellowing is usually a sign of Nitrogen def unless late in flower. Purple stems can be temps and strain too.

I've seen several of these kind of photos but only for potassium. Might you know where I can find similar ones for nitrogen and phosphorus?

Aren't the deposits in municipal pipe systems mostly made of calcium and magnesium?

Yes, but in the case of calcium carbonate (chalk) it's inaccessable for a plant. In the case of an organic growth the microbes may break it down.
It depends on your water (what's already in there), your medium (what's already int here) and the stage of your plants development.
So the answer isn't easy or definite. It's better to learn to read plants and then go from there....
Epsom Salt is 16% Mg 10% S which is needed more in flowering/late flowering than in veg. Mg Def is easy to spot.

Thanks much! Plants are tough to read but a good read none the less!
