cal/mag like spots

Did anybody figure out if this was the LED being too close?

How much Bot. Cal/Mag+ did you end up having to use per gallon to stop the affects?

Same issue, pro grow 180- 22" away

Doesn't matter the distance for me because of my low ppm tapwater, without calmag i got a deficiency real quick.

You wouldn't think the height would matter, I've just been on this for a while and ruled damn near everything out.

I run RO (12ppm base) with Cal/mag- started off with 150ppm as a basis and I had gotten spots.

So I up'd it to 180 and the same thing, if not worse.

Now I have taken it back to 100ppm and the problems persist, not as severe- but there.

Just wanted to catch an idea of what others are putting in their water (CalMag wise) when runnin similar setups

-ml/gal.
-ppm

How much does ever body use in your rig?
