I definitely would give that plant some Mg. From what I've seen and read, yellowing (chlorosis) usually doesn't improve if there's no green left. The plant should have a healthier overall appearance, though.how often until symptoms clear? Or in other words, roughly how long does a single corrective feeding take to offer visual feedback of its efficacy?
Thanks man. Gonna do that today. If this were your plant, would you do epsom isolated or add it into your calmag?I definitely would give that plant some Mg.

Heard alot of good things about it never tried it though but you may also consider if there is something else locking out the Mag just a considerationOther thing because I’m so damned mathematical minded to a fault is how much ppm of empsom to use as a corrective.
Many say as high as a tablespoon. Well turns out a tablespoon of epsom is like 1800ppm or something. Can’t remember. I just put an eighth of a teaspoon into a gallon and it boosted the ppm by 175. That’s still more mag than they need on an ongoing, every water basis, which makes me think it’s probably enough. But I’m open to bumping that up to 350, or 525 or whatever. A single half teaspoon of epsom to a gallon would be about 700ppm. Seems like overkill but this is totally new to me..
Yeah I’ve thought about that but can’t actually figure it out if so. Water ph is always good. Nutes are a little hot in the soil (not feeding them yet..). Ultimately I doubt it, unless adding calmag at 200ppm to my RO in general would be causing an excess of calcium. Kinda doubt it. Seems rather likely it’s a mag deficiency..Heard alot of good things about it never tried it though but you may also consider if there is something else locking out the Mag just a consideration
Maybe it could be excess potassiumYeah I’ve thought about that but can’t actually figure it out if so. Water ph is always good. Nutes are a little hot in the soil (not feeding them yet..).

Totally agree here too much light could be your issue tooI'd turn the light down.

I mostly use Epsom salt for Mg and gypsum for Ca. In this case, I'd just use Mg and keep an eye on it till the plant is healthy.Thanks man. Gonna do that today. If this were your plant, would you do epsom isolated or add it into your calmag?
Roots organic calmag. Derived from keserite and gypsum. No nitrigen in it.What mineral additive are you using to replace micro nutrients stripped from R.O water?
As you have given this plant Epsom salts or cal-mag. I'm not sure your issue is Magnesium. I'm thinking possibly light burn as the lower leaves seem to be OK. Leaves look quite washed out from to much light. What light are you using and how far above plant tops? Power setting?..
What medium is the plant in, what you feeding? How much, how often?
You can top dress with a teaspoon of Dolomite lime and a teaspoon of Gypsum.
This will take care of Calcium, Magnesium, Iron and a few others for 3 or 4 months.
Do it again when you flip.
How much epsom do you use if you’re workin’ on a deficiency?I mostly use Epsom salt for Mg and gypsum for Ca. In this case, I'd just use Mg and keep an eye on it till the plant is healthy.
Agreed about the lay of the leaves. They were laying flat actually until I did the topping. Possible thy needed reduced light intensity from that for longer than I thought.Looking at the plant the over all color looks good, so that rules out a lot. The edges of the leaves are showing burn so that suggest over feeding. You said your not feeding and soil is hot, so that kinda explains that. Over all structure of the leaves on the plant are not flat or slightly praying, this indicated you have too much light on them. I don't see a mag deficiency, but I am old and color blind, so better pics would be helpful.
