This is still the same case that ive placed on many threads.
Flowering 5th week. 2 plants suddenly DRY out. I thought it was the ballaster, that was burning them, but now i firmly believe it is the tapwater that made soil WAY too acid. Im trying to get a ph meter, but i will have to wait 2-3 days to get it so i need a solution NOW because 2 other plants are starting to have the same signs as the ones that died.

I need to make something before i get the ph meter or this will be chaos (prolly lose 4 plants if not).
How could i raise the ph so that it reaches aprox 6.8?
I know that right now i need to fill the troubleshooting thing, BUT its stupid because io dont really have PH of the soil.
How much calcium carbonate-limestone- do i need to add so that i change the PH? (make it higher)Should it be added to the water? (i will try to get a water source of aprox 6.5)or in the soil?
