Let’s see inside. I want to see your roots
You didn’t mention the most important factors.
Are u using beneficial bacteria?
Or are u using a clean mineral salt nutrient.
Furthermore, are you using tap water.
What ppm is your nutrients / PH….
What calmag are you using?
If you answer these questions in order, I’ll tell you exactly what’s going on here.
Also, don’t submerge your rockwool, are u using a top fed method?
Rockwool requires a flud and drain or a top fed, not an undercurrent. Rockwool shouldn’t be submerged fully in water.
If it’s mildly way or bumby along with the light color likely too much nitrogen
