Underfed ? Defiency

[hugrem]

I have one plant that started having some bottom leave yellowing , just wondering what could be the cause , is it asking for more food ? Or could it be a mg def ?

That looks like a cal/mag deficiency to me

Might have too or dig in some epsom salts into the top of the soil to give it a boost.

.... it's Mg defc, but we need more pics, whole plant and leaves to help confirm,...as to why, when adding Ca-Mg needs to be determined... this is usually a pH or nute build-up issue, but on occasion some plants need extra,.... BTW, there's no such thing as Ca-Mg defc. per se,... they often occur together, but not always, and they are very different in how and where they manifest,.. Ca is immobile, Mg fully mobile within the plant,....
