Hi my friend,

I using also Coco and GH Trio. Important to now how is your Tap Water you watering with? I using Osmosis Water highly recommended because you know exactly how waht you feeding with when you mixing your nutes with your Water. Do you using cheap Coco brand?

I feeding always 0.3 EC Calmag and than half dosage of GH total EC in vege 1.0-1.3
Test your runoff EC and tell me how high it is please no ppm.

Got a ec tsd meter delivered today and tested run off the digital reading says EC 2690
Then underneath that it says us/cm 23.6°c
Then if I press the shift button on meter it says 1345 ppm 23.8°c
Came with limited instructions so don't fully understand the reading
Does this make any sense to you fietchen ?
