Ok I re-took the brix readings at about the same time as yesterday and I used Graytail's method. I will be picking up a mortar and pestol tomorrow. I had to use 2 butter knives to squish between, it was still a challenge but I got some juice drops. The Tangerine was blurred between 13 and 14. The Tikal was a touch above 12. That seems more in line with how they "look". Scrubby you were right on.
Bingo!
12+ is what I would expect for those plants, but I didn't get a good close look at the leaf shine and turgidity.
They're hooked up and ready to rock!
