Yes, no, maybe so.
Pruning off damaged leaves for mobile nutrient def will show more quickly if changes made were effective. I pruned for light at the same time so I cut off all the reserves. Thing is there is/was plenty of Ca in the feed and its the pH thats causing issues. So the pruning has actually led me to the root cause.
If I were going to let it ride and make no changes I wouldn't have pruned, the reserves would still be there and the plant still would not be uptaking the amount of Ca needed. It would look better though.
