Cindy i was watching your other thread about nitrogen .for Tomato plants ,
a pair of Ideas for you , might be ,
Magnesium Hydroxide ,, Phillips milk of Magnesia , The trace element and regular milk from a Cow , changes to Chlorophyll and Nitrogen ,
This of course , leads to another which is Calcium ,
Water your plants with a mix of above as they grow over 6 or 8 inches and if their looking healthy , enough to cloud up the water should do ,
Half coffee Grounds ( I know and I talk about these also Cindy ) half potting starter mix ,, My special water play , and Wallah ,, A Sprout
,, AHA!!!
I Got One ,,
Bamboo Sprout ,
Your other thread Cindy , About Too much is it could be locked in to the soil Earth ,,,Try a Dissolved Vitamin C and a piece of potato Mixed up to see if that will release the elements to your plants ,,Magnesium and Calcium have to Hydrate to release to your plants , Acidity Ionization has to occur for that to happen ,
Melon rinds I was told once are a source of Manganese ,, Some forms are more difficult to get because it is used in Explosives !!!
