Please help identify?

Anyone know what this is ?

.

Looks like Ca def - try Cal/mag.

.

I have tried calmag I'll hit her again

.

The roughage will never go away, you just want to keep it from spreading. Keep up with the calmag.

.

Get a strong lens magnifier.
Turn the leaf over.
What do you see?

Will pull out the 1000x mag and post pic

Here are pics 1000x times top and bottom

wait ! Using nectar of the gods ? If that’s the case the ph needs to be 6.1-6.5 ph …slurries need to be between 6.1-6.5 ph and ppm 250-500….

pH problem.

Thanks I bet it was when I was foiler feeding

Calcium gets locked out at 6.2 if I remember correctly, in soil.

It's not cal mag and not ph ??

I need a picture of the entire plant. First it's not a Ca (calcium) deficit. Those are orange or brown punctate spots. Next it might be an atypical presentation of a Mg (magnesium) deficit, which presents as barred, interveinal chlorosis, but those are more of a light yellow because it is the loss of chlorophyll in the interveinal space.

Most likely it is pH as @MickFoster pointed out.

I only see one leaf so I'm not sure what your plant looks like and growth stage. If you are in veg you don't need Mammoth P. If I had to guess I'd suggest finding out exactly what the recommended pH for your soil is and dial that in immediately. I'd do that first before anything else if the problem isn't advancing.

Further hitting her with a dose of epsom salts (unscented) won't hurt if it is advancing. But correct that pH first.

NB old damage on leaves is not repaired. I hope this is helpful

Here is hole plant

Looks good and she's very young, so get rid of the P supplement. There's no progression so it's pH or possibly you got the lights too close, they are pretty sensitive to light when they are that young.

Is that the only plant experiencing the issue? If so, could be plant specific. If its a soil borne issue, fungus, mold, virus, or bad bacteria causing disease, you may try 100% all natural, all-in-one Eliminator insecticide & fungicide at https://doctorzymes.com/wizard. It will get rid of it without use of harmful chemicals, clogging oils, killer pesticides, residue soaps, and other unnatural ingredients.

Yes only one experiencing it out of 5

I OVERDOSED on calmag 2 days ago - today I got the SAME leaves as you (It is very likely a PH problem). I overdosed because my calmag is organic and my PPM meter was showing wrong values, I didnt know PPM meters dont really work with organic nutes.

My plants are autoflowers on day 15. I am waiting whether th yellow spots spread. If they spread, I will flush with RO water.

P..S I am a total newb, but I looked in many forums for why my middle leaves have yellow/greyish patches - PH issue was the most common answer
