Lights Landrace Auto Grow

Hey boss , upon further research of the strains I am growing I realized the Siberian Ruderalis was not a photoperiod and is actually auto. Since autos should be in their final pot I was already messing up by having her in a solo cup I suppose.

I transplanted, had a little issue with that as the bottom roots all the way at the bottom of the cup separated from the rest of the soil breaking some roots :confused:

If this where to be a PH issue how do I fix a PH issue? flushing??
although I suspect this is just a rough transplant
