So my pH kit FINALLY came in (ended up being backordered twice blah bla..) and appears my tap water is fairly acidic. Somewhere in neighborhood of 6.0 even. So now looking for a cheap pH raiser that won't harm plants.. Runoff of plants is like 6.25 or less so I probably have some nute lockout already occuring. Plants are in soil but so I guess I could water thru some lime but trying not to buy anything more or potentially over alkaline my soil. Any home remedies?
