I'm growing in coco 70 30. It's my first time using it. I was using ocean forest from the beginning. Also the nutrients that I use is organic. I also saw people online reading their threads that some of them raise the pH as the weeks ago by.New meter sounds good.
I'd dim the light to 50%. Full power right from the start is a lot with that 600w model.
A ph of 5.5 is very low for soil. I feel comfortable with 6 to 6.2, another user suggested 5.8 to 6.2 in another thread. Pick a number and stick with it.
If the ph is too low, the plant can't make use of the nutrients.
