First
Merry Christmas to all
So I am not sure what is going on with this plant or if I should do something
It is Fat Batard from bilburn
It is 48 days above soil
Started feeding Bergmans Flowertime about 5 days ago
Last runoff was PPM 1133, PH 6.6
On a couple of leaves are starting to discolor in center toward ends
Any help or pointers would be much appreciated
Thankyou
Mark
Is that one leaf the only one that has an issue? If there are no insects eating it and it’s the only leaf I wouldn’t worry about it. Merry Christmas 
I agree with @Flitme , but if you are worried you could do a lite epsom salt ammend or topping
Thankyou
I am starting to notice it on a couple of other leaves.
How would I do a light epsom salt amend and topping, and what would that be used to cure, just to put in the knowledge bank.
Thankyou
Mark
General rule of thumb would say 1 tablespoon per 5 litres of water can make for a great foliar application every other week. Difficult soils that have a pH above 7 will naturally lock out calcium and magnesium ions, so amending with some Epsoms salts is a great idea
Thankyou
I did the epsom spray today
Next feed I will sprinkle a little bit onto soil and will also start using cal mag
Thankyou

Epsom salts doesn’t dissolve in cold water so you need to put it in hot tap water (about 40C) to make it dissolve. Then add that to some cold water and use it on the plants.
Thankyou
Will do
Looks like a magnesium deficiency. Easy enough to remedy. 
Looks like they got you!
Hopefully the Cal Mag will take care of that
