You have a furnace? Use the condensation run off unless it's fixed to the drain pipe. Basicly distilled water

Thanks for the replies and likes MW.
I love the idea of free distilled water, but I'm not sure I quite dare mess with the furnace riggings. Let alone drag big containers of water around, seeing as you can stand up in the basement haha. Thank you though

I ended up hitting the ones with the leaf necrosis with a 2 ml dose of Cal/mag each. I also cut all the dead leaves and the ones I knew wouldn't make it.

Hopefully that helps.
