Magnesium deficiency?

[higher self]

Dim your light down to 50%‐65٪

Bummer,well you'd think the soil is good for pH.Your water is bottled right?

What about light,I assume you pulled it back?

Im stumped ,fresh dirt should be happy as all get out.

I was kind of hoping the new soil would fix me up....
Unfortunately I switched back to my tap water from the bottled water once I transplanted them. I'm still on the fence for my tap water being the culprit.
My light is 24 inches above canopy @ 50ish%... 480W fixture dimmed to 220W

I've got a big bag of Magnesium Sulfate I can dip into...

What size tent is that

4x4x6.5 tent

Epsom salts in water, mist down a few as and they will green right up. My tap water 450ppm mostly calcium, l add 50 to 75ppm and up to 150ppms Epsom salt to res every watering. Leds make them use more cal so need mag to offset it. Less is always more is a good rule. Can always stop using anytime you want, l buy the big bag! Poor man's calmag! Black Swallow is a few blocks from me. Buy most add ons from them! Ewc etc.

I went for Neem cake and Karanja and left with 3 cu ft of soil and rice hulls instead. Forgot the Karanja. lmao

tap water ph is currently 6.8...

Are you growing LED? Are you within optimum VPD levels?

at or near 25° and 64%

I'd try cal mag and iron EDTA. Looks like what i experienced in coco once

Start spraying close to lights off with Epsom salts in water ph'd to 6.5-7, also water with 1 tsp per gal of water. All my plants were looking like this until I started using Epsom salts. I use it every watering now or they start looking like this in a week or so

Should be good,for shits and giggles do a paste test on your new dirt.Distilled water make a runny paste let sit and check ph.

Your tap water is 400ppm ish? Do you have a report to see whats exactly in that 400ppm?

6.2ish soil ph
Sprayed with 2 tsp/L epsom, twice... not sure I see any difference as of yet, though. lol

no report as of yet.... and yes, 400-450ish ppm

So pretty hard water,is it from a well?

 

[steve870]

this is what my iron edta fixed

 

[LordEnki]

municipal water. 80% ground water. Apparently harder than most of the country.

So your back to bottled? Id find out whats in your tap water.Most likely its causing your issues.

Not sure what hes trying to say, lol.

The only reason I ask, is whenever my VPD has been incorrect, I’ve had all sorts of issues with nutrient uptake, especially when using LED. My approach is to fix VPD if incorrect, and take it from there. Hope you get it sorted

I believe they are implying I may have an iron deficiency, but I believe my PH isn't high enough...
I'm dialling in my blumats, and the pot was a little dry... maybe I have an under watering issue?
The other plant seems to be doing well.
I dont think the epsom foliars helped, so...
I think this ones a clone of a bag seed, so I'm fine whether it lives or not, but I wouldn't mind knowing why it dies.
