I'll keep an eye on that. Thanks. :)
I've been using pH strips for pH testing, and as far as I could tell, I've been adjusting the pH to about 6. pH strips? Yeah. Ha. It's difficult to get a hold of much else where I'm currently living. It's amazing that I was able to get a hold of GH nutes for the coco. The bottles were way more expensive than they should've been.
The drops pH test kits are inexpensive.
The pH in he root zone is what is important. Overfeeding and other issues can cause much lower pH than what you're giving them.
Thanks. I'll test the runoff after the next watering, but pH test strips are all I've got. I'm currently in a developing country, and it's not always easy to get my hands on everything I need. I do have some pH up/down from GH, though, so that's what I've been using to adjust the pH as needed.
