cannabis can take a beating and comes back - just this season I had a problem with corn borers in my garden- had 5 plants chewed almost completely into from the inside out- all were flat on the ground- only the skin of the stalk remained- I put some stakes in the ground next to plants- raised gently- tied to stakes and taped wounded area wuth painters tape- made of paper- I have done this before this year also- the plants were stressed and did not produce as much as non borer plants but they survived 10 weeks after injury until harvest which was 2 days ago -I think you will be fine
