Yes. Worth it? I’m not sure. You have to do it while your plants are still in the ground so the cover crop gets enough growth before winter. When you dig it in in spring inevitably some survives and I do have patches colonising the plot now so keep that in mind. I didn’t bother this winter just mulched over everything. -

I used to grow with cold roots more than everyone for ignorance. 17.5c -19c was my last winter run bottom root temperature + water at 14-17C. No heat mat, just tube heater. Light on was so so but light off was cold. Now Outdoor in pot (0.5-1l) with 3c night and 10c day. Never had similar issues. You are watering in Coco and I assume you check the EC run off and i assume the water distribution of your plant is correct ( including watering from top) and you EC intake consider the initial water Ec ( you are experienced so should be yes). I assume your EC and pH tester are calibrated ( mine fuck up after 2 years with 0.2 EC difference). To me seems burn by fertilisers due to EC but not necessarily because you added to much, but because the Coco is not flushing via run off and you have accumulation of salt nutrients somewhere. EC intake high, EC run off over 0.3 intake, PH above 6.5, dont you do wet-dry with coco isn't? If Coco doesn't flush properly (5-20% runoff depending of fertigation frequency)( a part that you are not working in hydroponic but soil with Coco!) you can build salt into the pot. Run off Is the technique to remove salt accumulation with fresh ossigenated new solution.
