Bottled water/seedlings

[THE BEAR]

Want to try using the bottled water and I'm wondering if this stuff would be OK to use if left open for 24 hour,
its for seedlings.

How does that add up with your fertilizer?

That all looks ok and well under the normal amounts you need. The bicarbonate is a bit of a concern as it may take more PH down than normal? I would not be afraid to try it. Is it cheap?
