PH not raising with Jack and RO water

[Whopflop]

I’m using Jacks 321 nutrients schedule for the first time and with RO water. Before nutrients the waters around 7.3PH and after it dropped to about 4.1PH. I let it sit over night and it was still at that 4.1 range. I’ve slowly been adding PH up but it doesn’t seem to be doing much for the amount I’ve added at this point. It’s a half gallon jar and I made sure to scale back the nutrient amount and checked the ppm and it’s where it should be. I’ve easily added a few tablespoons of PH up but all in 1-2 ML portions and with about 15 minutes in between and the PH only ever went up to about 5.1, before crashing again and now sitting at 4.6. I’m still fairly new to this whole process so any help is appreciated, Thank you.

Incase anyone runs into this issue I solved it for myself. I was using Humboldt secret ph up. I put a calibrated ph probe in it and it went up, so I know it’s not bad. I made a new batch and used baking soda instead and it immediately fixed all my issues.

i'm starting a dwc bubbler bucket now and intend to use jacks in distilled water.
i'm using the 321 three part recipe and ading silica and microbes.
just in the seedling stage now, so running straight DW pH around 6.5 with some microbes.
i'm wondering what ppm you will be using and which stages?
i'm going to folow the kootsMed reccomendaions and start at 25% when i start seeing some roots come out of the cube...

do you have a grow diary?

good luck with the grow
