Does anyone have any idea what these dots that started to appear on my upper leaves are? I was thinking too much calcium but I am at a loss. Please tag some people to help lol

Here you go
Are you using any cal-mag? Looks like
The onset of a calcium deficiency

Yes use calmag on water days
What’s your ph and ppm coming out?

6.1 out 900ppm
hmmm. Your numbers look good. What distance is your light at? I had something similar with my white widows, I believe it was caused by the high Intensity lights and showed a calcium issue like this .

I don’t see anything major going on. When did you flush last? My first thought was nute excess but runoff TDS is good.

Flushed 2 days ago with sledgehammer
Something is going on @Myfriendis410.
Take a peek.
@Watt-Sun This doesn’t look like a Cal-mag issue to me. It looks like Phosphorus deficiency.

How do I add more phosphorus
Entirely possible that is a P def but occurred weeks ago. Leaves won’t recover FYI. OP may be providing enough now.

I have removed the leaves before. To be honest it occurs on water days when I give calmag that’s why I was thinking excess cal
Ok so I just watered with calmag
In 6.9 386
Out 5.8 1357
@Myfriendis410 @MrPeat @Watt-Sun
When your runoff gets up to 1,800 to 2,000 ppm it’s time to do water-only until it drops back to 1,100 or so (in soil). This will keep your salt levels at a good level. Once soil is depleted you will have to treat medium as soilless and supplement accordingly.

I flushed it yesterday because that was on the ff schedule

the new growth is looking alright to me, like they say, damaged leaves stay damaged or get worse
I read something somewhere saying if you remove fan leaves during a deficiency it can spread to other fans is this true or false?
First off, I’d do a defoliate of fans and strip lower 1/3 of plant. I would suggest nute burn that occurred 2 or 3 weeks ago. It will likely progress somewhat more but so far I don’t see where it will affect harvest. I assume you are on the flowering schedule?
One thing; plants are unable to process nutrients well under lower light conditions. I would consider your light just fine for veg but inadequate to provide enough light for dense flower. Light drives all processes and the plant simply can’t metabolize higher salt levels in the medium. You might drop your TDS of input to 850-950 ppm or so. Especially autos which respond to lower salt levels anyway.
