Hi, I was wondering how long you can store your mixed feed for. Currently I make up my water/nutes feed every day (around 2L). Could I make a weeks worth of feed (like a batch of 10L - 12L) and store it in bottles until I need it, or does it ‘go off’ if not used within a certain time frame?

Thanks
