Root base split?

[Shizznat]

So I got this split I noticed. Plants had a rough go. Ran outta water once. Froze once. Way high ppms once. All my fault tho. Been watching like a hawk ph and ppm levels and changing my bad habits so it's made a good recovery. That split however. 2 days in flower. Harlequin strain. Topped early and manifolded. Anyone seen that base split? It's in a 2 gallon bucket I wanted to try instead of 5 gallon. Thought I could make it work and save some nute money. I think the 2 gallons a better fit for autos
