Cool Slower growth in 4th month

Hi all,

I've noticed that after 4 months, my plants starting to grow slower than before.
I didn't change anything, so I assume it is now the time to add fertilizer?

2nd and 3rd month, I practically had to trim every week (plants almost doubled it size)

CO2 & Light are pretty much constant (except if you think the light deteriorated that much after four months)



What do you think?

If you haven't been fertilizing, then that's it.

Start by measuring NO3... and add if it is zero.

Add a nice trace element mix to the soup...

Consider potassium if your swords start to develop holes...

Add some plant tabs to root feeders (rosette plants, like swords, crypts, etc.)

Measure PO4 to make sure it's not the limiting factor.

That's what I would do... in that sequence.

Aah.. now that you mentioned it... the rotala macrandra leaves have holes and falling apart...
I thought it was iron deficiency, now I know!

Thanks!

Iron deficiencies manifest themselves as chlorosis (yellowish or pale areas between veins).

If you have soft water, you might also want to look into Calcium and Magnesium... I am not sure though how to measure and dose that.

I am thinking of adding a quarter cup of crushed coral to one of my canister filters, and monitor how that affects KH and GH. I have very soft tap water.

I am thinking this would also add Ca and Mg to the water, would it not?

Yeah, technically you could be killing two birds with one stone if it all works out.

1/4 cup seems to be the figure I heard from a few LFS people for a 90g.
