i know vinegar for ph down, what else?

main Q is a PH up? baking soda? if so 'bout how much per 0.1 change per gallon? and what other home products will PH up?

why i'm asking is i'm 26d into flower (she is lookin purdy) and after i add my (i know) MG bloom booster i'm at 6.3-6.4 and from 'the stoney chart' for soil i need to be at least 6.5 or better to get more P into my roots

nuther Q is i bought some 'House Of Herbs : blackstrap molasses'

do i mix as normal (1350-1400ppm (by my meter)) then add the molasses?
do i do the molasses in a gallon first, check the ppm then add the BB to my 1350-1400?

dunno what it is but NO MATTER what when i use the search function i get 'sorry no matches found' (cept one time it worked) and i have done it 10's of times, searching titles or whole thread, for words i know will trigger( PH, ak47, thc, etc etc) probably something on my end for sure

thanks in advance on the above questions

The term you search on must be at least 4 letters long. So the three items you listed above would not return any results.

I don't think a dose of molasses would change the ph and I think people add it after testing the water.

easily found locally ph down adjusters include citric acid, which is sold at grocery stores in the canning department, and sulfuric acid, which is sold at auto parts stores.

For ph up 100% lye, sodium hydroxide is the most effective.

how much to use to get a desired ph shift depends entirely on the water being adjusted. If you have a water quality analysis you can use this Alkalinity calculator to approximate.

I've seen it posted that vinegar is ok for soil but not for hydro. I was using vinegar for a while before I got some ph down, and I noticed that after a few days, water in a container that was buffered down to 6.5, when rechecked ,would read 7.5 or better. It took a few days, so I don't know if that would matter with soil.
