With that much leaf damage I'd suspect some sort of caterpillar. 🤘😤

I have brown spots on some leaves lower down on plant. Have looked it up on internet and think it calcium deficiency. But I use Cal Mag. Could it be something else? I have picture up on diary.

Why are all the leaves on the upper half of the plant perky and the half way down start drooping off? Even the ones getting plenty of light. The soil is not that dry yet either.

Spots on this one leaf
Can anyone provide some inside into what these spots on the leaf may be from? I know there was slight nute burn as multiple tips have indicated, but this is the only leaf I've seen with these spots. Thanks in advance!

Fertiliser burn
A few leaves of my bush have this little brown spots on them, I googled this and made a conclusion that it is a fertiliser burn. I assume it was done with “Root booster”. Can I continue using vegetation fertiliser? Do I need to remove damaged leaves? Any other actions needed?
