A couple weeks ago one of my Magic Melons completely gave up on transporting nutrients to 2 of its branches. The plant looks like it’s diverting any resources it would send to these branches to the rest of this plant. The branches themselves are still alive, but forming significantly dwarfed flowers.
They are connected to the main-stem without breakage. There is no bug damage visible on the stunted branches themselves. The rest of the plant has no signs of anything unhealthy. I’m in a 200 gal smart pot, with a coco-heavy soil mix, and have been feeding tea brews, cal mag, and sea blast grow/bloom as well as spraying fish hydroslate.
This issue appeared after 2 weeks of wildfire smoke that nearly blocked out the sun.
So my main thoughts are that either I had a fusarium or pyth problem that only effected the roots that power the 2 branches that are no longer getting nutrients. That maybe I corrected the developing root rot by altering my watering to compensate for the wildfire smoke after I saw that far less water was evaporating from the run-off around each pot. Or, that some sort of bug chewed through the roots associated with the stunted branches. Or, that the roots for those branches broke through the floor of the smart pot and found themselves growing in oxygen deprived clay and decomposing granite and are dying.
If anyone has seen this before, and isolated the cause, I would love to know so I can prevent this from occurring ever again.
