In post #4 you said the recipe was for Early Blight and Ca++ doesn't ave anything to do with EB infection.

perhaps your grandad was thinking of BER ( blossom end rot) which for years was thought to be due to a Ca++ deficiency but the last 20 yers oaf research have shown that that's not true/

There's no problrm with uptake of Ca++ thru the roots, the problem is the bad distribution of Ca++ with in the plant itself and that occurs to the many stresses that a plant canhave such as uneven water delivery, too much N, growing in too rich soils, too hot, too cold, too wet and too dry.

As plants mature they can better handle those stresses which is why it's usually only the first fruits that are affected.

The only time that adding Ca++ migh help is if a soil analysis shows that there's NO Ca++ in the soil or if the soil is so acidic that Ca++ is bound in the soil and both of those conditions are quite rare.

Hope that helps. And not editing b'c it's too darn hot in this room right now.
