Skunk Auto - First time topping

After defoliating, the nute burn started. Coinciding with defoliation, I also switched light schedule from 20/4 to 14/10 because of working in the office. My theory on this: with full leaves and lots of daylight hours to process nutrients, my nute levels were fine. The double whammy of less light and fewer leaves caused nute burn. To help remedy, I flushed twice two days apart and run off ph was 6.3. Now I have spotting and continued leaf damage, but this time apparently due to either lockout, or a lack of nutes in flushed soil. Adding cal mag back into the waterings now, hoping it’s enough. Should I also add the Tiger bloom back at this point? Half of leaves are curling at the tip. Only a fraction of leaves show the lockout damage so far.
