Ok, so here's a follow-up question's follow-up, lol.
What are you using to test the runoff? A lot hinges on it being an accurate number. If you are giving us color-coded results, we may be giving you the wrong advise.

But to answer your question...if you are putting in at 6.3 and it comes out at 5.3...your mix is buffered more twords a mulch/compost than a potting mix.
If it is buffered at 6.0 or lower, I doubt lowering your water ph will work immediatelly. The buffer(s) in your potting mix will still fight to bring down your ph.

What potting mix are you using, and did you add any ammendments?
Do you have access to a 'normal' potting soil for a transplant?
Rusty Trichome Reviewed by Rusty Trichome on . Tricky PH question Hey, so a lot of different material tells you to use different PH levels. So I wanted to find out what is the best one. From the research so far, these are the reasons: 1. Different plants use nutrients at various ph levels 2. depending on whenever you use soil or hydro the ph should be different. ph for soil systems should be 6.0-6.5 and hydro should be 5.5-6.0 I guess the reason the soil PH should be higher is due to the soil lowering it to the needs of the plant. However, how do you Rating: 5
