I always say start with the basics, And pH is a basic. If you look over my thread
You'll see similar coloring in the beginning of my grow and I had major pH issues.

And in hydro it's really specific.

Also did you buffer the pH in the rockwool cubes? Usually have to let them soak 48 hours in a 5.5 to 5.7 ph'd water aolution.

@GoAuto6 no I didn`t and never have done...ive prob just got away with it for years, looking at it the start is the most
important bit. glad I put the post up and thanks for the knowledgeable reply
