How Much PH Up is Too Much?

After adding Roots Organics Buddha Bloom to my water, the PH drops about 3.5 points to 4.7.

I used Earth Juice Natural Up in the amount of 1.5 teaspoons to bring it up somewhere between 6.0 and 6.3. I'm guessing that many others have had to deal with this issue and am wondering if I'm using too much PH up? My soil PH is 6.8-7.0.

I am growing organic (water only) but I'm having to add extra nutrients to my soil for the last 3-4 weeks and so I'm using Roots Organics for the first time. I have read that you do not need to adjust the PH of your water with organic soil but, 4.7 seems too low to me (bad for microbes I think).

I have made this PH adjustment 3 times to my plants and haven't noticed any problems.

Diluted in how much nutrient/water mixture?

Try making a single batch of nutrients without modifying pH, and leave it overnight. See what the pH is after 12-24 hours. If the pH is closer to the target, try it again, scaling back the amount of wait time, until you get to the point where you know exactly how long it takes for stabilization to occur.

Many nutrients will drive the pH down, but go back up again if the mixture is left to sit for a while.
 
When I used RO water I would mix it about 3 Or 4 to 1 with tap water to get a perfect ph with my nutrients. I don’t use RO anymore but I do the same thing with rainwater

It is 1.5 teaspoons per gallon of water. I'll give your advice a try and see if the PH will rise over a 12-24 hour period after mixing the nutrients. Thanks.

If (and I do mean if) it does settle at a higher pH, like I said, try it for shorter periods. It's possible that it may only need to sit still for a very short period.

Or, it might not have the pH up effect whatsoever. I'm just always looking for solutions to eliminate the need to add anything to my water that isn't completely necessary, and this is one that has definitely worked for me (that said, I've never used your nutrients).

It's been 24 hours and letting the water+nutrients sit out for 24 hours had zero effect: PH = 4.5 before and after.

I noticed you said you are growing organically. Any particular reason why you’re bottle feeding? I grow organically as well, I use roots organic dry amendments “ grow and bloom “, the P and K ratios are too low for my liking, so I supplement with guano and kelp. I very rarely have ph levels drop that significantly. I use tap water, and after adding my kelp and guano, the ph drops to 6.2-6.4 at the lowest. One drop of ph up and I’m back to 6.5 in no time. Buddha bloom is kind of weak in P and K anyway, I think guano and kelp would be better.

My soil didn't have enough nutrients to see it thru the entire flowering period. I'm trying to find a super soil that doesn't need additional nutrients, so I will see what happens next grow. I've got three more super soil recipes to try.

I've never had PH levels drop like they did with Roots Buddha Bloom either.

If I need additional nutrients on a future grow, I won't be using Roots Organic Buddha Bloom - probably use True Bloom instead.
