Weird brown markings on my plants

Plz help

Hi
I cannot say for certain as to the brown spots. But my best guess would be calcium. If they need that they usually want magnesium too.

The flowering pics look good. You still have 2-3+ weeks. The 3rd and 4th pic seem farther along than the last pic. That last one needs more time. Good work.

Thanks heaps mate
