Quick nutrition question Haifa and Yara fertilizers

[singlorigin]

So my last grow was 2 years a go, and i have forgotten my nutrition usage in Flower.
For Yara i cant finde any suggestions on dosage so the closest fertilizer mix i found was Jacks .
Some input if im doing it correctly
1. Yara Kristalon Orange - Part A
2. Haifa Calc - Part B
Im mixing them based on Jacks Fertilizer chart 321
1 - 3.7 grams on 4 L
2 - 2.5 grams on 4 L


I have forgotten Epson salt - what should be the dosage for it ?

For MOAB im using : the recepie i found in Forum
Mix of Haifa MKP and Haifa MAP.

it contains 3% mgO.. not even sure you need it. cal nitrate you need for sure
i don't see yara advise mgso4, but with some og/cookie strains mag def can appear

what strain do you grow?

i'm also interested in using yara dry salts
i would use some epsom but in moderate quantities and wait to see

what bother me with yara is the iron content .. here they say 0.07%, it's low
