Hello,

my little ladies are about 14 days old, organic soil, karma's pink zowahh.
A plant is showing small yellow speckles on the outer edges of the lower leaves. What could this be?
I'm using cresciene Fluxshield 100W LED, 30-35cm away dimmed to 50%, they should get something around 300-350ppfd. Thanks in advance.

It's not a trait of Chem, or any strain. It's probably lockout from too much Ca, and Mg mainly. From your hard water, plus the dolomite and the fertilizer you added.

I'd water it really good and flush it out bit. I would bet it will get better if you water the shit out of it even with your hard water. You shouldn't have added the lime, but what's done is done. Your water already has liming properties.

Some of that looks like P deficiency. A pic of the whole plant would help though.
Dolomite lime is pretty terrible as a top dress. You get all the Mg first followed by Ca skewing the Ca:Mg ratio all throughout the grow.

I don't know who started the trend with feeding Dolomite water solution and other nonsense? Dolomite lime needs to be cooked and broken down to give the correct Ca:Mg ratio.

It's like some new Cannabis growers completely ignore well known and common gardening practices? There's too many YouTube "experts" and growers without any real education in agriculture.

All 4 of these plants are the same strain, seeds germinated at the same time, same environment, same substrate, nutes, light, etc, etc.

What the heck is wrong with the obviously unhappy one?

The best suggestion I've had so far is to repot it in fresh material. I'll be doing this while looking for root aphids.

The other guess is some kind of virus, although I've looked at a lot of pics of HLVd and this doesn't fit any of them.

So what gives? Any and all ideas will be considered but I've ruled out mold, mildew, pythium and bugs.

Here's a pic of the roots;

Okay so no root aphids. Good! But I shit canned the plant anyway because I don't like how it looks.

If you still got the specimen I would check in the middle of the root core to see any dark areas indicating fusarium.

The wilt looks similar to plants I've had years ago.
It was never wilted, it was just wrinkly and wouldn't grow. It had some brownish spots. The roots looked fine all the way through- the root ball wasn't very big either. I was scared of a virus from seed so I disposed of it. Maybe that was just paranoia but the rest of my plants are all pretty healthy so why take a chance?

Just curious as to what temps you kept them at
