First Time Issue... Progressing fast

New member but long time lurker. Been growing for about 6-7 years and im always learning something new or dealing with new issues.

I've scoured Google and nutrient deficiency issues but can't seem to find my issue. See images attached which got exponentially worse over the last few days.

Growing Cannatonic CBD in FFOF under my 8 bulb fluorescent veg light. Super super light feeding for the first time just 2 days ago, prior was just PhD water and cut some clones off today.

Everything's in my basement which is unheated and I'm wondering if it's the really cold temps down there. I've had my seedling heat pad wrapped around the plant for the last month.

The leaf deterioration is my major concern. Had minor leaf tip yellowing over the last couple days, of guessing I fed her too early. No bugs this time of year, saw 1 stink bug crawling on it about 1 week ago

I'll defer to Batman and Robin when they arrive.
My 1st guess is she could use some Epsom salt.

Please, no disrespect intended. Just a couple names of good growers on here who know this plant inside and out.
Thank you for your response to help the op.
Peace.

My first thought was calmag, but lately seems cliche.

Well it appears to be a magnesium issue and many will suggest cal/mag which will work.

A picture of the whole plant might help.

Cannabis in FFOF in veg when not given nutes will usually run into a need for magnesium and or nitrogen not Calcium.
A mistake many growers make IMO is to not separate the two (cal & mag) when talking about a problem.

It might be a mag problem or a calcium problem but cal/mag IMO should not be called a plant issue.

With the batman thing, just a joke.
I can't figure out which one should be Batman.

Wait this is a FFOF issue. I'm Batman. Renfro is Robin and OldMed is Alfred.

Lights are an 8 bulb 4ft T5 setup with veg bulbs, temps are in the 50s in the basement but I just lowered the light even more and she's wrapped with a seed mat, humidity is 45-50% (I burn wood as main heat source which keeps air really dry during winter). I can't imagine there being a calmag or nutrient lockout issue, I usually only run into that after the plants been in FFOF for 3+ months but could be a bad batch of soil I guess.

I've got another 600W MH bulb if y'all think I should put her under that, it would definitely heat things up. I've never used the MH bulb because I use the 600W HPS bulb and system for flowering but have nothing under flower at the moment

Weird.
When I take a close look at the yellowing it looks not just yellow but cut out.
With Mg the leaf material is usually smooth but yellowing not dug out like that.
Not sure if it is a Mg type of issue. It's an unusual look to me.

Correct.... the leaf looks like it's lost all its "meat".... Agonist like it's lost all cell and water retaining ability

Here's a few more updates photos. The leaves effected are brittle and crumble when touched. I just took clones a couple days ago and the new growth looks good but I'm worried about those larger fan leaves

Nice pictures. IDK what it is but someone will eventually have seen it before.
I'm subbed!
