I have been experiencing some incredible growth rates using the aea foliar x balanced amended soil. Im wondering if I need to hit them harder or more often with foliars to keep up with the speed of growth. Possibly they are showing these symptoms because of accelerated growth and maybe they are unable to uptake the needed boron quickly enough?
Interesting regarding your perspective about the hollow petioles/stems. Only thing I can relate is quite a few years back talking to Kempf about his Photomag and alfalfa. He said one of the benefits of use is alfalfa stems would fill out thus increasing yield. Growers with favorable growing seasons were also getting an extra cutting per year.
Great looking plants, awesome growth rate.
I will say we finally got a bottle of Rejuvenate that didn't blow up in shipment. Seems they did tweak the formula a bit or at least this is a new batch.
I can't provide any sap feedback this year and only anecdotal. For various reasons the soil mix at 3 locations not what we would have liked yet still getting awesome results with the foliar program which includes PHT calcium and phosphorous, Photomag, Seastim, Seashield, Rejuvenate, Albion calcium, Ca-25 and Sea-Crop. Everyone using the program noting a big difference this year
Next year our focus will be better soil and some sap testing.
