pH too low!!!!!!

Just wondering as the pH of my plants are about 5.5 what I can do to make it higher!! I need major help here and any would be appreciated!!

Hello? Can anyone help? any way to change it with home made stuff?

5.5 to 6.5 is what i aim for.

are you soil or hydro? depending on the way you are growing you will have to raise the ph by adding water that has either a higher or lower ph than what you have now. so just ph some water, then if its low add ph UP, if its low add ph DOWN and water your plants. you learn to kind of guestimate what you have to do to get you ph where it needs to be and take a shot at adjusting it to where you want it

they have ph test kits and ph up and down at petsmart, walmart etc

baking soda or tums raise ph (just make sure they're fully dissolved).
