Will this water be ok to give my plants?

Ideally, you would have a lower pH in your water. High pH water won't screw you over right away, but in time I think it increases the pH of the soil, which would require adding sulfur.

Pure water is slightly acidic at 6.8.

 

Your water hardness comes to about 7 grains per gallon.....that's not bad as all

And the tds is fine....just add 2-3 drops of ph down per gallon and you will have very good water

 

that is pretty much a myth...in order to lower the ph even a little bit you need alot of lemon juice.....and at that point the water is too bitter and can kill plants

I suggest just ordering one of these.....alot of gardening stores and hydroponic stores carry this too

Amazon.com: General Hydroponics GH1514 Ph Control Kit: Patio, Lawn & Garden

my ph is normally at 7.3 and i add 2 drops per gallong of the ph down and im at a perfect 6.8-6.9

 

that PH is just fine if you have compost-based soil (10-30 percent compost)

 

What hope2toke said!

What method of growing are you going to employ?

 

Check your soil pH to get a more accurate reading of what the pH the plants will actually be taking up. Take some of the soil you are planning on using and mix a cup of half pH adjusted water and half soil. Stir it up and let it sit there for 10-15 mins and then take the pH of the mixture. Alot of times it will be lower than the pH of the water that you used, so if it still is within the acceptable ranges then you know what pH to adjust your water to. If it is too high or low then adjust your water acordingly and it should make it so that the pH of the soil solution is just right. If you change soils then you'd want to do it again and maybe even for different bags of the same brand of soil just in case they are slightly different.

 

no matter what kind of soil you use.....7.6 is still a bit too high

 

compost you make yourself.....

grass clippings, plants that were cut down, leaves, cow manure, chicken poo, etc....

thats the only kinda compost i know of

 

Read the fine print about ph

 

No it doesn't. You would need to add about 25% of either worm castings or compost.

 

No it doesn't count

 

I would go for roots organic soil. FFOF has been giving me strange results for the past year and I made the switch and couldnt be happoer. As far as your water goes, add 1/4 tspn epsom salt to even out the cal/mag or you will start seeing deficiencies. Try not to over-water and good luck!
