So I noticed multiple of my nutes from different companies and different npk ratios product lowers my pH water a lot! People say pH needs to be 5.5 to 7.0 when feeding but I noticed when adding nutes to water, it lowers it sometimes down to 3.0 pH. For example my water would be like 9.5 pH before any nutes. Once added and mixed to my desire of let’s say 980 ppm, the pH now will be like 3.8 pH. Even lower if my fresh water is like 8.2 pH, it’ll go down to like 2.5 pH. This is with multiple nutes from different companies. I use fuel flower, big Cannahuna bloom booster, fox farm beastie bloomz and their trio, cal mag plus, fish fertilizer. All of them have different npk some with no nitrogen and high pk and some has low nitrogen and high pk ratios. So is it suppose to be like that? I don’t know how to adjust the pH once nutes are added except adding more water but then that lowers Ppm.
Is your feeding product suppose to lower PH?

It shouldn’t be that big a swing unless you’re putting too much fertilizer in.
But yes, most bottled nutes will lower the PH.

Sorry I forgot to mention I used my water filtering system machine thing to get a higher pH to see if the high pH would balance out the pH to around 6.0 when around 900ppm but it doesn't. But my regular tap from faucet is like 8.5

Like jjgrow420 said, 2.5 is basically vinegar and that's so unlikely that I'd check the PH meter.
Also you wrote: "This is with multiple nutes from different companies. I use fuel flower, big Cannahuna bloom booster, fox farm beastie bloomz and their trio, cal mag plus, fish fertilizer."
That is a ridiculous amount of nutes no matter that the ppm/ec is. You've got N in CalMag, N in the fish fertilizer, N in the trio, plus your likely tripling up on the P/K with the bloom nutes ... it's just way too much. I don't think it could bring the PH down that far, but it can get it into the 4's if you overdo it.
I'd start with the ph meter. Make sure that is correct. Then I'd rethink how you're feeding. I use one bottle, Floranova Bloom and nothing else. It has everything, saves money, and is easy to use.

Get yourself a well rounded nutrient and drop all that extra work. I use 1/4 tsp Maxibloom in seedling, slowly add 1/4 more each week til I reach 1 tsp. My tap balances perfectly, never checked it again after first look.

Yes, nutes lower ph, but that's a lot. If I had to guess on the biggest contributor, I'd say it's the fish emulsion, which is generally very acidic. Use ph up instead of trying to add add alkalinity during the filtration process, as you have no idea what minerals or their respective amounts that are added during the filtration process.

Can we see some pictures of the plants. Are they big that’s a lot of food.

9.5pH down to 3.5 is a hell of a swing. I'd do some experimenting and nail down which product is the main cause. Then not use it.
