I feel ya. Reading plants can't exactly be taught. But they will show you if you're listening lolYes, 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.
