I noticed today that some of my secondary vines have split right down the middle is this something to be worried about? and whats causeing this? Should i leave them open or cover them up with soil?
many on here will tell you to put captain, or some type of fungicide, then some will say bury, some will say not bury. Just make sure you let it heal for a while, couple of days, then its up to you.
The split (long ways on vine) really does nothing restricting, as you lose (almost) no potential volume.
