mountain sping water

im new to this first time grower,and im using mountain spring water should i check th ph in it?

Unless you purchase distilled water, the ph can be far from 7. If you are growing in soil, it likely won't be an issue. If you are working in a soiless or hydroponic medium-- yes check the ph. I would also say that if you have a hydroponic system, you are well advised to get a reverse osmosis (RO) water filter.

Good luck!

growing in soil they seem to be doing great,thanks for the help
