Ph problem need help

i tested my ph before watering (6.5) now my soil is an 8 and plant look a little crappy. how should i lower my soil ph

Sulfur? aluminum sulfate?

always test the pH of water before you water, us pH down to get your water ph at 6.5-7. then water.

if you cant get ph down, vinegar works aswell.

Sulfur? aluminum sulfate? what do you mean

Add either one to lower soil ph.

Be careful Search the web for how to use this material.

How much should i add

Add anything thats acidic. Vinegar works great, or concentrated lime juice in the small neon green plastic bottles from the grocery store used for making mixed drinks:] fresh lemons.. fresh limes.. etc.

I swear i read that aluminum sulfate can also help turn blue strains more blue.

What are you using to test your pH?

Hope it's not one of those soil meters with the probes. They are seldom accurate.

Wet

you didnt mention if you added any nutes as that will usually raise your ph. in any case adjust your water lower than 6.5 until your soil runoff is arpund 6.5-6.8. what kind of soil are you using? rich soil can accomplish both of your issues.
