Dwc Cal/Mag
Newbie54started grow question 4y ago
How much cal/mag do plants of this size need weekly in DWC? I'm using Advanced Nutrients pH Perfect and have supplemented it with Canna Mono Calcium / Mono Mag.. it looks like there might be too much calcium now.. or lockout pH was under 5.6 for a week, now I've raised it to 6.1.

EC .2-.3 of cal-mag is a good starting point.
It is also dependent on your water, how much calcium/mag is in your base nutrients, and how much base nutrients you use.
With botanicare nutrients I aim for 140-160 PPMs ( EC .3) with my water + cal-mag.

Deficiencies while in late flowering during flushing periodThere is deficiency going on (looks like cal) she is an auto flowering strain in her 9th week and been flushed for a week now. Should I give her cal/mag and stop the flushing or is it too late to deal with that? She looks like she will be ready to chop in a week or so.

Hungry? N deficiency?So this sort of just happened overnight. Plants were very thirsty this morning and noticed a handful of leaves that are fading.
I fed them 1tbs of dr earths flower girl and 4ml of calmag in a gallon split between the 2. Should I add some of their 4-4-4 as well?
