My heads to mashed for numbers to compute right now…honestly it’s much easier with mono mg 

 

 

I’ve also read a few contradictory statements regarding how much mg is actually available in a gram of Epsom salt. I think it really depends on how much mg% & s% is available in the chemical make up of the salts. Typically 9.7% mg & 13% s.

 

 

I’m sure it’s 1 gram of Epsom/1 litre water - 97ppm

 

 

Morning mate  I've bought myself a couple of 25L containers to bring up to room temp and pre-mix in the Epsom salt. I truly believe that this math would have been a breeze for me, 30 years ago   However, that was 30 years ago

 

I'm currently at 100ppm Ca and 0ppm Mg 

1g Epsom per 1 litre water creates 97ppm Mg

So I would need to add approximately one third of a gram Epsom per litre, I think?

Would give me approx. 100:32 which is close to 3:1 

Does that sound right?  My brain hurts, I'm sorry

Yeah 0.3g is close enough. 
 

Im not sure if your saw one of oldbears recent posts regarding ratios? He recommends 3:1 up to week 5 of flower then 2.5:1 from week 5, then bringing it to 2:1 in late flower and flush.
