i think you want it at 6.5 ,i think if you look online you get the recipes for household stuff that can fix p h such as vinegar(to bring it down) i cant remember of the top of my head what to use to put it back up but, if as i said you look online you'll sort it

do you have lime in your soil? if so, it doesn't matter as much as some folks think.

spots could be from a def. or bad ph fluctuation.. When using soil i always water til i get at least a 3rd run off.. This helps to keep salt buildup down as well as keeping the ph stable..
