Watching nutrient levels
 

Hello, Greg Watson's PMDD formula should be arriving Monday and I was
wondering how should I go about measuring the nutrient levels? I
already have a test kit for nitrate but what about other nutrients?

Try Tom Barrs formula with 50% water changes weekly, much cheaper and
simpler than screwing with test kits. With only a bit of adjustment you can
work out what is best from that point.

Under dosing or unbalanced dosing generally causes more touble than ever
dosing.

Health fast growing plants will beat algae everything if nurients are fairly
well balanced.

All the dosing instructions I've seen are for each compound separately.
I was assuming that the PMDD from Greg Watson was 1# of various
fertilizers mixed together. Is this how it is, and would someone have a
link to T. Barr's formula? Thanks

Yes, that's the way to go. One point though, get your tap water tested
so you know where you're starting from for the purpose of adding ferts
is to bring your levels up to where youwant them to be from where they
are.

Some tapwater is high in phosphate so you wouldn't want to add any
if it's fine out of the tap. If your water is very hard you won't
want to add MgSO4 ("Epsom salts"); if your water is soft, you do.

Once you know the difference between where you are and where you
want to be it should be easy to figure out what to add each week.

I use distilled water because the tap water is ridiculously high in
phosphates. So I guess I would have to add all the compounds since
there's not any nutrients in the water I'm adding.

You use nothing but distilled water? I'm shocked anything is still
alive.

LOL, Of course I add nutrients. I use flourish and iron tabs to
fertilize. I also have pressurized co2 running.

Yeah but with nothing to buffer the pH I'm surprised it doesn't
turn into an acidic bubbling mess.
