Hey.
The issue you are having is adding your high Ca tap water to your 6/9. If you are going to use your tap water you need to use "General Hydroponics Flora Micro for Hardwater". This contains no Ca. You are doubling the Ca that H3ad recommends. He used the 6/9 with little to no Ca from his tap. All his Ca comes from the "GH Micro". He doesn't alternate his feedings with nutes then non nutes either. This defeats the whole purpose of using coco. H3ad also used pure coco. Read his thread. Then read it again.
Focus on these post from him.

yo growers,
I'm running my first coco grow, and unfortunately run into some problems. Some of my plants shows some kind of deficiency.
here are the details
-12/12 from rooted clone
-5,5l pot
-coco dtw, 30% perlite, hidroton mulch
-tap water (0,5EC, 108mg/l CaO)
-watering every day with 20-40% runoff, 2days feed, 1 plain water)
-Heads modified coco formula (6ml/9ml/gal micro bloom) PH'ed with phosphoric acid)
-pH 5,9
-EC 1,4. (raised from 1.1 few days ago)
-runoff pH: 6,8-7 EC: 0,8-0,9
Really need your help, I dont know what the fuck is going on with the plants.
