Magnesium deficiency?

[NPK]

I didn't get any pics of the spotting; only just saw it last night for the first time. The calcium deficiency was surely in effect before I got the Cal-Mag in the tank. I now know calcium is slow-acting because it's an immobile element. :wink:

Sorry to rebring this older thread up, but I'm curious if NPK was ever able to resolve this situation? I'm going through the same thing right now. I'm just wondering how long recovery took once you added CalMag? Any other info would be great...


Thanks!
