trouble with soil ph, need help

So I've got 6 plants that have been vegging in fox farm ocean forest soil for 2 months now, and I've always given them water and fox farm nutes ph'd to 6.5. For all visual purposes the look GREAT. nice, green. and leafy.

After watering them today I checked the runoff of the soil and it was a deep orange, around 5ish. So I flushed all the plants (10inch pots, 3gallons?) with about 8 gallons of water and the ph of the runoff coming out still does not look "light green" or 6.5, but more of a 5.9- 6.0 "yellow".

Am I missing something? It just seems like that should have brought the ph all the way up... What else should I do to fix my runoff ph or is this normal? Do i just need to start adding lime when watering and let it rise that way? I've got them all back in the lights and drying out now so Thxs for the help

I wouldn't fret too much bout the run-off if your plants are looking healthy. If you want to add it via watering you can topdress your soil and then water, or mix it with water and then water, but its not the most water soluble thing out there.

Im not sure how much you need if mixing with a gallon of water.

If your soil has no lime already, then 1 tablespoon per gallon of soil would suffice. Topdress it and then water.

Whatever option you choose, id start out light and see if that gets you to your desired ph. Its easy to add more if necessary, but good luck getting rid of it if you use too much. Id probably start out with a teaspoon either way and go from there.
