PH testing water with nutrients.

[Quantonium]

Heya!

Quick question. When I add my Bio-grow nutrients to my tap water, it becomes brown. To test PH, I then use a GHE liquid test indicator. I take a vial, add some water, and some PH-test-solution, and the color changes according to what PH the water is. My question is, does the fact that the water is brown change the color of the PH-test water after I've added the solution?

My tap water is around 8.0 PH. I added 2-3 ML of nutrient to 1 L of tap water, and checked the PH. It was at 6.5. Very convenient, so I hope that is the actual PH, and not that it is just "lowered" by the fact that the water was brown to begin with.

In my opinion ifin yu mix vodka and orange juice together and dump it down yur gullit yu be dumpin vodka and orange juice not just the orange juice so yup it be the way i do it cause it be the actual thin yu be dumpin on yur plants. So I would sugest yu mix yur mix and test it before yu use it. If yu mix yur nutes with water and test it THEN yu add lemon juice and pour it on yur plants the ph would be different from what yu tested thus not acurate. I also test the water run off be comin out the bottom of the pots after waterin to be seein what the soil be holdin fur ph. Good luck pilgrem hope yu be doin great with yur grow good luck and be safe.

You can't accurately ph tinted water when using one of those color-coded test kits. The tinting skews the results.

You might want to adjust your ingoing water to the high end of the ph range, (7.0 or so) and then add the nutrients. The nutrients will bring your ph down further, but ph should still be in the acceptable range. If you start to see the leaves curl ('the claw) or some yellowing...raise the water ph a tad more before adding the nutrients. The plants will let you know if that's ok. :thumbsup:

Was this what you were asking...?

Yeah, that sounds like plan. I've bought a syringe now as well, so now I can know exactly how much ML i put into the water. Handy!

Oh, and I just noticed I got a reply from biobizz on the matter.

"Biobizz are 100% organic products, there is no need for pH leveling. That is why working with Biobizz is intended to be easy. You do not need to worry about Ec and pH levels."

So it seems I should take it down to 6.5, and hope that works. If not, I'll just do what you said :)
