magnesium

[Peteey010]

Can someone in the know confirm that I've got a magnesium deficiency please.I just want to be sure before I give her some Epsom salts.It started from the upper fan leaves and is slowly spreading downwards

How's your pH? If you haven't already, check your run off and make sure your pH is where it should be and that you don't have a nutrient lockout going on. I see some red on the leaf stems which could either be genetic or a sign that phosphorus is being locked out. If the pH is good, then magnesium and calcium, so a cal/mag supplement or molasses and epsom salts. Those small red dots indicate a lack of calcium.

Next question where can I get molasses in the UK I've looked everywhere

 

[briman]

Grocery store. look for unsulphered backstrap molasses. Should be with the baking/syrup. Shouldn't cost too much either.
I would hit a grow sore and get some actual cal/mag. it will work faster and depending on the brand, would hit em with a 5ml per gallon for it to work faster, but read the instructions. I'm in the Americas and not too sure what they sell across the pond.

Got mine in a corner shop(used in Asian cooking) . If you cant find any, for a bit more you can get some in Holland and Brett or other health food shops.

Molasses goes by a different name in the UK, I believe it's called treacle.

Holland and baretts stock molasses, as do most health food stores.
