RE: [APD] Vallis problems

Is the lack of potassium also consistent with the rotting of the leaves?

I remember when starting to dabble with K2SO4, I hunted for a potassium
test kit, and I think one of them would be next to impossible to get
hold of.  I'm going to see if adding daily doses changes anything (I'm
assuming I should split the weekly dose across 7 days?)

You mention sticking fern/palm plant spike into the roots...  could you
elaborate please?  How would this help?  What kind of fern/palm?  I can
imagine vals zapping out nutrients, but I wish they could zap a little
more NO3 ;o)

Quite possibly. Can you get a test kit? I've seen val do this sometimes
with
uneven fetilization, that is it may be using it up all at once by
growing
at a pretty good rate then it runs out of K and while trying to sustain
large leaf growth, fumbles and makes the deforemd leaves characteristic
of a K deficiency.

WHat you could tru is dosing daily in small amounts of potassium and see
if
that changes the nature of the problem.

Or, stick a fern/palm plant spike in the roots. I've found val to be
an outrageously heavy feeder.

Only change one thing at once! (Or you'll never know what did it)

Val has always been weird for me. It'll sit there and do nothing
for the longest time, making a crypt look like a fast growing plant
then all off a sudden it explodes and there's val everywhere and
either I yank it all out or concede the fact there's nothing but
val in that tank.
