Coffee filter is not gonna work. Get a ph pen.
RT's right and sorry I was so buzzed I forgot to mention it, because it's very important, but I mix my soil up several weeks, sometimes months in advance and let it sit and fester for awhile before I actually use it....I use all kinds of organic garbage to get the ph perfect before it ever sees a root, plus perlite and vermiculite, and let it sit for some time to be sure I got it right! I'm an oddball tho...and don't have access to good bagged soil! If you can get good soil that is truly 6.3, definitely use it!
