Hey DS :smokebuds:
Do you have any Epsom salt or sulphur-free blackstrap molasses? Both of those are natural cal/mag supplements and can be used in the meantime until your cal/mag arrives.
I think your lady might benefit from switching to a 20/4 light cycle so that she has some time to recoup every day, especially if she's dealing with a deficiency. Do you have any other safe means of supplementing heat at night?
