Not sure what your setup is.........

If you are in soil,coco, or soiless medium you could use a product from Green Light.
It isnt a hydro shop nute so it's super cheap..$5.00 a bottle the name of it is Iron and soil acidifier ( Iron Sulfate)....Add 1/2 teaspoon per quart or 2 teaspoons per gallon to drop medium ph by 1/2 point....If you want it down to 6 from 7 add 1 teaspoon per quart...

This is just my two cents............You could always look for a product that contains aluminum sulfate this will lower ph too....

IMO if the medium's ph is off running low ph water will not lower it long term, once it is in the medium it will usually acclimate itself to the medium and give the same reading 1 day later.........

I agree with sophisto about that, the products you are using to lower your pH will not work well, it's a temp solution that has to be reused daily and which will cause problems if you have to water everyday....... if depending on your setup is soil.......

What soil are you using> what brand?

Using pH down phosphoric acid will work fine, just make sure whatever you use it lists 0 sodium no sodium added.

You have access to a hydro shop?

Thanks for the info sophisto and Stitch. There is a hydro shop that I go to, but wont be able to go there for about another week. The soil I'm using is MG Organic mix. I really don't see what the big fuss about MG is. It's worked fine for me and I've had problems with pretty much every other soil available at Home Depot or those types of stores. I feed them Fox Farm Big Bloom every watering at 2-3 tablespoon per gallon and Tiger Bloom once a week at recomended dosage. Sorry I forgot to add this information earlier but I was pretty baked. :joint:
This has to be a temporary fix for I can't get to a hydro shop for about another week. The nearest one is about an hour away, so it's not right down the road. any temporary fix suggestions?
thanks again!

Finally someone agrees, if it is USED PROPERLY it will work, if you listen to there directions, no wonder you get pissed at them!

I used there seed starter mixtures and will recommend it forever as long as it's not changed like there regular potting mixture.

Your fox farm big bloom could have caused it to rise you using that amount, I can't remember if it was akaline or acidic, can someone please refresh my memory on that?
I used it in flowering but it's been years since I years that......
