Yes that was my mistake too.500ml is enough for exactly one lady, my calculations are not accurate as I can't know how much water I will be giving in two weeks time, praying Jha that I get money in time
Sorry my friend.
If you absolutely have too before the new bottles arrive you could add extra water to the nutrients to stretch them.
Mix 1 ml in 2 litres instead of 1 litre.
It's not great for them.
But it's better than just water.
But until the bottles arrive its something you can do to stretch your nutrients.
I'd never recommend this but your in a unique situation.
Stay safe
