hows it all just a watched a vido on cocco coir and a we thing thay did was take a e,c reading of the coir all thay did was take 1500 ml soil top up with water to 2000ml stir and let sit for 2 hours filter [coffee filters] then take your reading if to high flush with water if to low increase nuts any feed buck would be great hop this helps and it might just help if the coir is allways at the right e,c 5.5 shit the water should be distilled water
