adjust ph before or after adding nutes?

[USbeginnerguy]

My apologies if this is a stupid question but i couldnt find an exact answer. Im using bio bizz grow/bloom/topmax
My first question is should i continue the Grow through flowering? I just went throughter my first week of flowering. Also should i check my PH before or after i add nutes to my jug of water? I have always just ph'd my water to added nutes and fed the plants. I recently was told that was wrong so im lookin

after, always ph after adding stuff and before you put in your plants

Ph the water before you add the nutes. Ph the water after the nutes are added. The next time you feed, adjust the ph of the water down where it needs to be BEFORE you add the nutes. After they are added the ph should be exactly where it needs to be if you adjusted it correctly before adding the nutes. This is why you need to PH before and after (at first) in order to get your baseline and know where you need the water's PH to be.

Is that with tap or just ro water?

sorry dude, but that is ridiculous, if I add my nutes to my water, 99% of the time it ph's out just fine. Your way, you are packing your water full of ph up and down.
I try to not have to use that stuff. If it goes low, I just add water.

you can't ph R/O water, it has no buffers in it, why you adjust AFTER adding stuff.

PH after nutes. Don't believe the hype of veg nutes flower nutes as long as you have a decent npk rating you don't need the extra money wasting bullshit. Of course.micro nutes and cal/mag. If you have that covered your golden. Don't starve your plants of nitrogen or etc in flower it only hurts the plants not help. It will quit up taking it when it does not need it. Keep it green keep it happy and happy growing

I use tap n always did it after chuck, thanks!

Answer: When first starting out it is a good idea to measure the pH of your water every day, until you get a feel for your system. Measure your water and then add your nutrients. Within an hour check the pH and adjust accordingly. Repeat this process until pH stabilizes. The liquid Flora Series has special pH buffers to help maintain a desirable pH. It is a good idea to note how much water, nutrients and pH modifiers are needed to obtain the desired values. After several "start- ups" you can generally get a feel for how much acid or base to use for your situation. Frequently pH stays within a desirable range for a considerable time, and then rapidly rises or falls to an extreme. This is usually an indication of the need to do a nutrient change. If you are using hard water, pH has the tendency to climb above 7.5. Sometimes this can be neutralized with acid, though one might consider adding a reverse osmosis unit in an extreme case.

adjust PH after

 

[az2000]

After you have a grow or two, try not phing. Soil has more buffers than what you pour in. It will pull the liquid to its ph before the ph will pull the soil to its. As long as you're not overfeeding (too high ppm) and the ph of the final solution isn't below 5.2, you shouldn't have to ph.

If you're using RO water, after a couple grows try adding tap water to get 150ppm initial starting water. You can eliminate calmag as a supplement and your final ph will come out higher.

Yep. And add a bit of dolomite and some worm castings to your medium mix and never worry about pH again.

I am not packing them full of anything. They are adjusted accordingly. If your water has a high PH to begin with, you will need to lower it so that whatever the nutes raise it, the PH is still lower than 7.0 and not lower than 6.5 (for soil) after the nutes are added. If your water has a low PH, it is possible that when you do add the nutes, it raises the PH to be exactly where it needs to be. This is just basic chemistry. Not everybody has the same water.

I dunno about what you use for a base but my base drops ph like a rock.
There is no need to ph water before mixing in MOST everything else.
it goes like this, add nutrients, ph , add Flying Skull z7 enzyme.
This is a first for me seeing anyone suggest adjusting ph before adding anything.

My tap is 7.3 ph, I add 4-5 ml. Per gallon of flora nova bloom and my ph is 5.9 - 6.0, works for me. Well used to, no more gh products for me.

I have a 35 gallon tank that I have to PH, it takes just a little more than a couple drops.

Just to be clear as there seems to be a bit of confusion. You do NOT want to add your PH solution (up or down) to your feed water. The straight shot of acid can react adversely with the nutes. This is why you want to ph before you add the food and give it time to dissipate. This is in the cases that you NEED to ph. If your water comes out at 8.0 and your nutes raise it 1.0, then you should ph your water down to 6.0 (5. if you are shooting for around 7.0 (6. before you add the nutes.

Why would you want to add acid to your feed water? Doesn't it make more sense to have the water ready to just add the nutes and then feed instead of adding acid to your feed water? This really isn't a difficult concept. Some mutha fuckers are always trying to ice-skate up hill.

um, wtf?

ALWAYS AND I DONT CARE WHAT ANYONE SAYS!! ALWAYS PH AFTER NUTRIENTS!! Nutrients 9 times out 10 will make your PH fluxuate... I promise you, try testing it... (not all nutes will do this, but most) PH before, then add your nutes, try PHing again... watch the difference... My nutes ive noticed (at least my flowering nutes) lower my PH more acidic, so if I p.h. my water to 5.8-6.0, then after adding and mixing nutes, it'd technically be 4.8-5.0 or worse... I always have to adjust accordingly.... Good luck man!
