388 if I am not wrong means you have a hard water situation from tap. That there is something I have not had to deal with so I'm not gonna lie to you.

I see you have the ebb & Grow system. That thing is the rats ass. Mine has 18 buckets atm and running really well. Make sure you clean and soak that new hydrotron in ph adjusted water. Keep checking the water you are soaking in till ph stabilizes at what you adjusted it to. New hydrotron can make ph drift upwards so thats why we soak :jointsmile:
