Could be phosphorus lockout.
Check the PH going in, and out.

Some strains will do this regardless of PH.
I don't know about Cheese B*mb.

Mine have had the same purple streaks all through veg- I tried to bump up the phosphorous and now the leaves are dark green around the veins and light green on the edge with a ton of leaf curl. Moral of the story: check your ph all around before supplementing
