Cal/Mag. deficient or lock out?

It's not necessary. I give water out of the tap as do others and everything is fine. Why would anyone have water of pH 5? Because they made it that way with pHing first, then using nutrients. People are wasting time playing the pH game. The directions of the back of nutrient container, to the best of my knowledge, never say "pH your water to (insert level here), then mix in these nutrients and feed your plants." Never do the companies say to do this. You'd think if pHing water were necessary the makers of these products would say so. They don't. Just because a pH of 5 makes aluminum doesn't mean I need to get my water down to 5.8. That's an erroneous assumption. People all over this world "grow things" and never pH water and don't know squat about chemistry. Oh look, the plants outside my house are dying because I didn't pH the water down the way people do when the grow dope. Oh gee, what to do now? What bullshit.

LOL..you are one lost puppy! No, people all over the world that do general gardening outside don't, they also don't feed with bottled nutes in concentrated form. Ask a farmer if he cares about ph! lol. No, he's not hand watering a hundred thousand plants with ph'd water, but his soil will be amended to make sure ph stays within range! I grow in containers and i don't have rainwater feeding the plants. Those little magic bottles filled with those colorful compounds we call food for plants, dont just magically go in the plant no matter what the condition of feeding water is! I won't waste my time replying to this, this is completely idiotic! Just a tip, no a nute bottle won't tell you to ph your water first then add nutes..you add your nutes then ph!

Blitz, you're wrong and you're misleading people here. You say you won't reply but your make a reply. They never say to pH water either before or after you add their product. How people got on this kick that pHing will help after adding nutrients, I don't know but it's become a disease in these grow forums. If pHing were necessary, there would be instructions on the container to pH to a particular level or number. That information, as far as I know, is never present on the container. What is present however, are words like "This product has pH buffers to improve nutrient effectiveness." The sellers of these products need the stuff to work or you'd buy it once and then never again. In my opinion, plants grow fine in a pH range in the 6's. The bottled nutrients will stay there provided you don't use too much. This is all a grower needs to understand. I've said this before and will do so again - get the nutrients right, don't overfeed, and you will be fine. It's when people get into the habit of over controlling the grow that they get into trouble. That what I keep seeing people do here. The idea of flushing with pH adjusted water seems silly, but people keep wanting to do this too.
