    RO pH when using Coco Coir and FF Nutes

    My RO water is 7.0. After I add Cal-Mag and Nutes, it drops to 4.0. Do I then need to raise it to 6.0 before giving to a plant in coco loco? Without buying the pH-UP, what's a good substitute? Thanks for your help!

    Update: Since I had a gallon of pH 4.0 nutrient-enriched water, and a very thirsty girl, I used baking soda to get to pH 6.0 and fed her well. While I did order some pH UP, I decided to use baking soda as this "grow" is an experiment to get my set-up working well. So, I decided to experiment with the baking soda fix for my pH problem. Whether a SWAG or an accurate answer, I appreciate all the feedback!

      I'm reluctant to try baking soda. I don't remember having read that it'll work with cannabis. I ordered some pH Up. Thanks for the response!

      I started bagseed in coco loco and another in kind soil. I really like the coco loco best. I've been pH'ing my water down and feeding tap water, no nutes, for a month, waiting for my nutes. Now that they're here, I need to increase the pH. I'll order the pH Up. Just trying to save some time. What's another couple of days. Using the bagseed to get my set-up right and practice a bit before I invest in quality seeds. Just ordered from Seedsman yesterday. Thank you for the instruction! Much appreciated!

      I had already bought the pH Down - my tap averages 8.2. I keep frogs and fish so, use it to get to neutral. I can easily see now why both are needed. Didn't realize that before I got started. Thanks, again, Green!
