APF UK EI starter kit option

[Jake5tar]

The figures appear to be incorrect for this product. Manufacturer instructions state a ratio of 4-1-6 teaspoons of KNO3, KH2PO4, MGSO4 respectively. Roughly 40g-5g-15g.
This option on the calculator computes:
19.02g KNO3 (roughly 4 teaspoons)
5.02 gKH2PO4 (roughly 1 teaspoon)
57.46g for MGSO4 - which is more like 12 teaspoons.

Not sure which option you mean as the Rotala Butterfly Calculator does not have APF UK EI starter kit as one entry, just APF UK Trace. Each manufacturer is free to have their own recommended dosing as they see fit... and each user free to ignore it . Posting a screenshot of the settings you input might help.

Mg dose should be adjusted based on the values of the tap water. Adding a little Mg is not bad but there may be a need to add more if you start from RO water or very low (<3mg/L) Mg.

Think I have posted in the wrong place
Was meant for the IFC fertiliser calculator thread on ukaps.org.
My bad....so sorry.
Don't seem to be able to delete it either. New to forum sorry.

Np, hope you get it clarified over there.

We have been looking into this but so far haven't been able to elucidate why these numbers are. I will answer in UKAPS forum once we find what is going on.
