Mag deficiency? Is it on lower or upper growth?

Got any Epsom salts ??? I would say that's a mag defiency 100%

Being as its on a large fan I'd say she's pulling it for the new growth, mag is one of the mobile nutes so if it's not getting it from the soil shell eat it from the reserves aka older leaves usually further down the plant, if you don't wanna water it in a couple nice foliar applications should alleviate it a tad but I'd just water it in with some bennies, I've never been comfortable spraying the plant unless I have to

I guess this one is a sucker for cal mag then ...I loaded it down with cal mag right up to it's last feeding with veg tea...thank you I'll try it and see what happens ...yeah these leaves are the lowest on the plant.

Go magnesium only if you can, looking nil as far as cal dediency
