Next question !- magnesium deficiency in tomatoes. Potato blight is all around ( chopped mine down yesterday) but according to this month's RHS magazine the patches on my tom leaves are definitely magnesium deficiency. Does anyone know what causes this please? I know it's said that conventional tomato feeds make the problem worse but in fact I hadn't even started feeding when it appeared. The tomatoes are in 2 Levington large growbags, 3 to a bag and each in bottomless pots with the contents of a third bag split between the pots. Plenty of fruit coming.
