Here is what I would do..
after transplanting, water with 7.0 or 7.5 ph'd water and check runoff.. Write down ph'd number and runoff number.
2 weeks later check runoff again. if runoff is lower than 6.0, adjust ph and water on next watering. write down numbers..
And then every 2 weeks later check again.. adjust ph and write down numbers..
and observe your plants..
When you have a list of numbers, you know when to change ph..
If this sounds so complicated and silly.. Just water with 7.0 ph'd water..
18toki Reviewed by 18toki on . PH question Alright I was finally able to obtain a digital ph meter, and as I suspected, my ph is quite low and I believe it to be the root of my other problems. This is my first grow, and I am using Fox Farm's Happy Frog soil (they were out of ocean blend or whatever). I ph'd my water to be at 6.5, then I flushed out my plants pretty good. I then tested the runoff and it came out 5.5. Does that mean my soil is 5.5, or is this the average of my soil and the water making my soil ph 4.5? How can I raise Rating: 5
