My ph is at 7.5 What can I do?

[Alvis11]

This is my first indoor soil grow. The ph is at 7.5. What is the easiest way to get my ph lower?

Thanks !!

If only temporary, (a week or two) lemon juice or white vinegar. But for long-term, you'll want something botanically sound like PhDown by General Hydroponics.
It's made from phosphoric acid (much safer than it sounds) and my plants love the stuff. 1/4 tsp:gallon brings my 8.0 water down to about 6.8...and one gallon of the stuff lasts me over two years.

egg shell is made up of calcium carbonate CaCO3...this is a base so it wouldnt lower pH

sorry, that ain't gonna do it ... even egg shells added to the soil, take months to break down ... besides, the pH needs to go 'Down', not up :wtf: ... your fertilized water, may start pulling the soil pH down, after a period of build-up, keep watching it ...otherwise, use something like GH 'pH Down' ... white vinegar will get you by, but it attracts bugs ... :smokin:
