When you turn a powerfull light on 24h/0 .You always have to be super aware about (sometimes severe) CAL/MAG deficiencies .
That's why 24/0 light cycle is not so recommended .
If you use them in mono nutrient it's 1 part of Mg for 2 part of Ca.
And for sure, all the other nutes have to follow .
Are your plants growing faster and bigger under cMH ?
So more Ca and Mg and nutes (than your habits) is logical .
Most of the nutes supplements or "boosters" on the market are N - Mg - Ca complexes .
I hope it helps .
