Hello people,
after getting great inspiration on my last thread I decided to make the next I am not 100% sure if this is the correct subforum for this question, so if it is not I apologize.
I am looking for a water-soluble calcium fertilizer as a single salt / powder. I dont want to use bottled nutrients.
Currently I use calcium nitrate as my source for both nitrogen and calcium. In veg and for moms it is perfect, but in flower when I wish to keep nitrogen low i use canna mono calcium. Canna mono calcium contains calcium oxide which afaik is not water-soluble so i am unsure how they do it.
Any ideas what i can use? Calcium chloride dihydrate?
Would really appreciate some help.
