Default Brown spots on leaves?

Hi Weldon. That was interesting info about potash, but you're right - it
still doesn't verify/explain why my leaves are getting brown spots. I guess
we can chalk it up to that old saying "too much of anything is not good".
Potash sounds like it should be great for plants, but in excess it probably
has the opposite affect. I am not very good at measuring, pretty relaxed
about it, actually, so I probably overdid it, thinking "if a little is good,
a lot should be great!" Thanks for the info.

It must be the potash since you have made that change just this year.

I am trying to figure out why potash would cause such a problem. Found
the following info, FWIW:

Potassium/Potash (K): Potassium protects plants against stresses.
Potassium protects plants from cold winter temperatures and helps them
to resist invasion by pests such as weeds and insects. Potassium stops
wilting, helps roots stay in one place and assists in transferring
food. Potassium is a regulator. It activates plant enzymes and ensures
the plant uses water efficiently. Potassium is also responsible for
making sure the food you buy is fresh. Where does K come from? The
element potassium is seventh in order of abundance in the Earth's
crust. Through long-term natural processes K filters into the oceans
and seas. Over time, these bodies of water evaporate, leaving behind
mineral deposits. Although some of these deposits are covered with
several thousands of feet of earth, it is mined as potash or potassium
chloride. Potash ore may be used without complex chemical conversion;
just some processing is necessary to remove impurities such as common
salt.

Maybe we need an agronomist.

I'm betting it's the potash, too, because it's the only thing that is

"new"
to my pond. I've been using baking soda for all of the four years the

pond
has been in existence, but only this year tried potash to help my plants.
Guess it backfired on me. And no, they don't look quite like the brown
spots you get from the heat, they're even on the leaves that haven't made

it
to the surface of the water yet. Besides, Connecticut isn't that hot.

I have seen the same thing in my small pond, the brown spots, that is.

AND, I tend to think it comes from the use of potash - maybe a little
too much - don't know. Gonna quit it for a while and see what happens
- or doesn't happen.

I also use baking soda to keep the ph above the acid range.

OTOH, it may be related to the awful heat here in Florida.?

It may be time to put a new Sears catalogue in the out house ;-)

I'm
sorry but could not resist.

IMO sounds like low iron.

I know it will be hard for you to answer this without all the

details
and specs of my pond, but maybe if you've had a similar experience it

will
ring a bell with you. I have a 4000 gallon pond in it's fourth year, and
everything is wonderful. Clear water, healthy fish, spawning, hatching,
lily buds, etc.

Within the past week I have added some potash and some baking

soda,
but not on the same day. Today I noticed that a LOT of the plants

leaves,
(hyacinth, lily pads) have lots of big brown patches on them, even the

lily
pads that are still UNDER the water. Did one of the two additives I put

in
do this or is it just coincidence? I can't imagine either of them
causing that kind of damage.
