Soil Runoff pH question

[infdjedi]

Hi All,

Quick question about pH of soil runoff water. I am using FFOF with a bit extra perlite in 3 gallon grow bags. I transplanted from cups to bags last week and watered last night for the first time. I pH'ed my water to 6.8, watered, and then tested the runoff. pH of the runoff was 6.1 - 5.9. Plants look great, but I am wondering if this will become a problem later on? If so, what could I do to alleviate this? I plan on transplanting in about another week or two into 5gl smart pots.. should I add some lime to the FFOF this time? Or, should I simply start watering with pH 7.1 water to try and even things out?

Thanks in advance!

good question I'm not 100 percent sure how to answer but i think aslong as you test your soil to make sure the pH is correct u should be fine

I would ph the water to 7.1 personally. Its hard to mix lime into an already going pot. On your next batch add some lime.

water will not change the ph of soil. the soil will buffer the water. you're fine

I also just started a grow 3 weeks ago using ffof, the soil in ph'd at 6.8, you should just water it for a month, unless your plants are asking for something, I learnt this the hard way!! just keep doing what your doing it will be fine, like scrog said!!
