| Hi im using a deep water culture hydro system for growing tomatoes. my tap water comes out at ph 7.9 with a carbonat hardness of 5 and EC 110-120 ppm tested myself. I was thinking about lowering my ph with citric acid to a ph like 6.8-7 first and then adding my nutrients to prevent possible reaction with the carbonate in my tap water. I tested this and it came out to a ph of 6.0 with added nutrients. What do u think about this methode ? Should i go the other way and add nutrients first and then lower the ph to 6.0 or is this maybe the better method ? |

| In case you didn't know there is a Hydroponics forum here and likely your best source of info on questions such as this. It is such a different method of growing compared to dirt gardening that few of us here can be helpful. Dave |

| Ia addition to the hydroponics forum there are numerous threads on acidifying water, and bicarbonates, in the Fruits forum. This is just one example: |

| Add your nutrients then adjust ph to where you want it. When i add any nutes to my soil grows i always adjust my ph to between 6.4 - 6.8 this is the range my plants do the best. |
