just read thru this whole thread. Damn!!
What background do you think brings the giant calyx trait ? I have the same thing going on with my Black Tuna , but I've seen it before in the past. maybe a "hybrid vigor" thing versus a genetics thing? Facinating though and sure makes for exceptional bud shots, which this thread is loaded with!
My tunas started busting the giant calyxes exploding with clumps of pistils, immediately following the addition of 1/4tspn per gallon of koolbloom to my lucas formula in week 5.
