after talking to my friend. you are right....its soooo strong that you wont need enough to really alter your food that much. my friend seems to think that the extra P in the cyco is what was causing his problems....i doubt it personally. (Just for the record though: Cyco ph down is 50% pure P)
Im not against ph'ing soil. I just dont recommend going down that road until needed. All good soils are coco and/or peat based and the ones that are peat based usually add lime , then you add all the good organic amendments and your ph will usually stabilize itself between 6.0 and 7 very quickly.
(reason being: coco and peat are almost the perfect PH for our world and they are both buffers so no matter what you put in (within reason), the soil will stabilize between 6 and 7)
Example: my tap is around 8 right now. I use it with no ph down. I just add whatever food i think they need.
Another great example: If using the Earthjuice 3 part "organic" line, then after mixing your food , the ph will be close to 4.0. Ive never seen problems giving them a ph of "4.0" from the meter. (that reading is not accurate on any meter)
Those are my own opinions and some facts. If you want to rule out ph completely , like most growers do, then you will go ahead and keep ph'ing your water as long as you use mostly chelated chems for food. (Real , organic foods will never read right with a ph "meter")
