Hi.

I am seeing some holes developing in some of my older Sword plant leaves and
have read this is due to K deficiency. Is this accurate? Can some of you
please share your experience of dosing with Potassium? Currently I have
SeaChem's Potassium Supplement and use it at not quite the recommended
dosage. What other factors could lead to a low K level?

Can you recommend a good, accurate K test kit?

Also, I am planning on stopping to use SeaChem's fertilizer products once my
ingridients for PMDD comes in. I have followed what thekrib.com says for
what to get and will be following the advice from this site as well about
how to dose. Any experience here will be appreciated.

For anyone that is using the PMDD mixing from The Krib, what kind of results
are you getting, and how long did it take for you to notice improvements in
your plants? What was there before state and what is there state now that
you have been dosing PMDD?

When dosing PMDD, did you stop other 3rd party fertilizers?

Thanks,
Jesse

In general the PMDD formula doesn't provide near enough Potassium.
Potassium should be at around 20 ppm. That means 20 ml of the Seachem
product for every 10 gallons. Use dry K2SO4 to dose Potassium.
