I don't know what any of those bottled products you listed are, so I can't comment on that... But, I do know a thing or two about organic gardening. Do you have more of those worm castings? If they are high quality castings (most sold in stores are not...), they should be loaded with plant-available calcium, and also plenty of magnesium. Lay down an inch of so of castings on top of your soil and water thoroughly. That should fix you right up.
There are plenty of ways to solve a cal or mag deficiency without spraying unknown crap on your plants. Eggshells+vinegar can be turned into a potent calcium supplement. Epsom salt is OK'd for organic production; it'll solve a magnesium deficiency quickly.
ok so turns out I forgot that i cut some of the badness off so I could keep track in case it gets worse, but this is the best i can do in the way of photos. Basically it is the very edges of the leaves going yellow/brown and some brown spots on the leaves. This is the older leaves. A few new leaves right at the top have a little interveinal chlorosis as well ie yellowing with green veins. Thanks in advance!
