Also you need to use 30% less nutrients for LED grows. I only discovered that today looking through my LED manual and I burnt mine early on by following the recommended dosage.

I have been using the GH trio for a few months and have never added anything else. Cal mag is more for the flowering period.
What's your ph? You should aim for between 5.5 and 6.5
The colour of the water only indicates what colour it is. Did you wash your clay pellets thoroughly before us? The colour of the water suggests you didn't and you should probably find some silt sediment at the bottom of the res. This is no major drama, but I would suggest cleaning your res and flushing your clay pellets a few times with PHd water, that is in the optimal ph zone.
It is vital that know your PH; probably the most vital aspect of all.
lol my bad. Do you have a colour chart to compare your sample with? It sounds like your initial sample was around 5 - 5.5 and currently about 6 - 6.5 and that is still within the range.
Just remember that your nutes should be 30% weaker thank recommended with LEDS. Also, where is your nitrogen?
