So it’s a hydrated lime ionically bonded with Mg to kinda slow release. That would tend to pull pH up given time. You don’t need that, and it seems that product does not fit your water source.
Dolomite lime would tend downwards but has high ratio of Mg to Ca that needs to be adjusted with another like gypsum, calcium carbonate (CaCO3), oyster flour (fossilized)
Gypsum doesn’t modify pH while providing Ca & S.
Epson Salt handles Mg & S.

I think these are the best combination for your alkaline water source. The BioBizz seems to nail it and swap to the Gyp and ES for Ca & Mg.

You have K def showing so Langbeinite is slow release K Mg & S.
Potassium sulfate is fast K & S. All above are in sulfate form and won’t adjust pH.
Calcium96 (Down to Earth) is a viable option for foliar applications but this wouldn’t help n flowering.
Im reading that you guys think dehumidifier water is bad, why is that? I use the water thats pumped out from my ac units in the house and have had decent results using that. Just curious if anybody is doing the same
Wassup bro, it’s most likely because it’s standing water and any standing water is a source of bacteria, mosquito larvae to form, dust/spores/pollen, and therefore is most likely unsafe for consumption, or your plants lol
I use the AC runoff on outdoor plants. Those also get micros replaced from rains.
It’s not necessarily harmful per se. It is distilled water, but the source is easily contaminated. The coils get coated in oils and aerial contams.
The water is missing in micronutrients the plants need most of all. No biggie if you replace them. Just better options for most people is all it comes down to.
Wow this is awesome @Budbrother thanks!
You guys have been a gem and a treasure of info. The troubleshooting on this forum is insane
I have epsom salt. This can cover Mg and S.
I think I’m good for Calcium, given how much is in there - and other Calcium products I have available.
I want to try finding Potassium Sulfate to use as a corrector, if I get it in time.
For next indoor grow, I’m ordering the Biobizz soil and following their schedule to the T.
Some have suggested I try GreenHouse slow release ferts for autos. As a low maintenance - set it and forget it approach. Sounds interesting to me as by spring-summer I’ll have dozens of different plants in my garden to look after. Anyone tried those?
It didn’t harm my plants in the beginning, per se. But if you use it without adding anything to it, it’ll leach the soil of nutrients.
My dehumidifier comes with a pre-filter, a HEPA filter, and UV-C lamp inside. It goes into a cycle of antibacterial maintenance and air purifying every few hours. It sits outside the grow tent, and I was not worried about it being a contamination hazard.
Pro: free water from thin air.
Cons: hassle to collect, store, correctly dose with micro nutrients, and you will end up correcting the pH anyway.
AC water drips outside, mosquitos and fungus gnats lay eggs in them and it also attracts other bugs.
In summer I used my AC water outlet as drip irrigation for cherry tomatoes
They kinda liked it, but so did the spider mites that took over.
I always thought the fluoride and whatever else is in our tap water would be more harmful than ac runoff but youve got me spooked with the spider mites post!
