Organic Living Coco grow. Help?

Looking at your diary it says coco and soil. Depending on how much soil you use it makes setting your ph a little tricky. I would say your 6.3 and 6.4 would be ok for coco/soil but they look a little underfed as well as your other issue. Now if your just reading the ph before it goes into the planter then it could be much different coming out of your planter. Next feed give enough so you have a little runoff water, collect that let it settle for a minute or 2 and check the ph and you can get an idea of where your ec is at while your at it. When you see your ph is out of whack, you will need to adjust it with some stuff that can bring your ph where it needs to be.
