Defiency magnesium

Hi I seem to have a mag defiency
I foilage fed some mag 2 days ago all new growth looks nice and healthy now
But the original leaves have still not changed will they resume there normal colour

Its possible but it doesn't matter.

Add a gram per gallon of epsom salt to your feeding regimen.

Epsom salt = magnesium sulfate heptahydrate (7 water molecules), a very inexpensive and well known mag and sulfur booster.

Mix it separately from anything containing calcium in solution.

Put it in the soil for the plant to uptake on its own terms. These are generally mobile nutrients.

I used epsom for a mag def once, it took a long time to see it take effect and change. WEnt and got some CaliMagic,saw improved effects in 2 days

in my experience the leaves will never be blade flat and deep shiney green once they have had some sort of set back.

i only tend to worry about new growth though as i like to focus all the energy into growing "up", those leaves will die and fall off naturally in the next couple of weeks anyway.

i think the leaf will yellow out and fall off

I use other nuts in the soil

Epsom salt is pretty benign and can be mixed with any of your other nutes, EXCEPT calcium nitrate.

If you're in soil, you can actually just sprinkle a few grams on the surface and water it in.

Lots of misinformation out there. Run 1-2 grams per gallon of epsom salt in your res and you'll be well below any possible threshold for flocculation.

The key is to mix the nutes into solution separately first, THEN add them into your res. This keeps solution strength to a minimum. Noobs pour all their concentrates into the bucket before adding water- and then wonder why they have trouble.

not to mention the fact it says on every bottle of nutes out there

I would just buy some calmag "plan magic" very affordable and guaranteed there will not be any impurities, like you might find in Epsom salt . I wouldn't use any foliar spray with nuts at the moment, it might damage the leafs that are going through deficiency.
Water your plant with only calmag (2ml per litre). With in 24 hours, you should start seeing signs of recovery. Next watering add calmag to your tap water until it will be at 200 PPM concentration. Than add your main nutrients.
