I regularly run into Calicum issues in my RDWC. My topping is often too much when I should just change out the Reservoir.
Seems I think when my plants get bigger they might be sucking all the calcium out that my Top-up schedule is not keeping up with
Seems some people may even add Cal/Mag to Masterblend or Jacks.
I had no ill effects of increasing Cal Nit by 30%. But not sure I would keep topping off at this Rate.
This adds Nitrogen Too, which my Plants do not seem to mind.
I wish I had a Calcium Meter so I could once add for all determine exactly how much Calcium my Bigger Plants are sucking out of the Nutrient Solution. I would like to know when topping if I also need to keep adding back some Cal-mag of Cal Nit?
One of my Bigger plants about a week from Flowering switch is probably wanting over 1300 PPM .5 conversion. I may construct an experiment by doing a 1300 PPM change out 2 days in a row one with 30% extra Calcium Nitrate -- no extra Magnesium, and one normal -- and then maybe one with Cal mag instead of Cal Nit?
The one that the plants drinks the most PPM's from would be the winner!
