In my experience easier to put these together than to brew a good fungal CT

Me too, much more than just curious!

Yes BUT if we dont try to improve the nutritional status, arent we then just
doing the same old treadmill thing that chemical agriculture is promoting
all the time - we have problems of disease and insect pests because of poor
or imbalanced nutrition - so we spray CT to combat the disease or bugs -
again and again and again - just like the guy down the road with his crop
protection chemicals! - Why apply a foliar treatment to a growing crop and
not look for a nutritional improvement? - to me this would be a waste of
time, resources, and opportunity. I would be really surprised if any good CT
was not doing this but with all the talk of testing (and the associated
costs) we should be looking at this. Its easy to do and cheap!

And they all are superb plant food too !

If this is available, by all means lets do it!

We should never neglect the nutritional effect of anything that we spray
onto our growing plants
