Potassium deficiency???

[MirandaB]

Hi All,
I'm running a lowish tech Rio 180 dosing liquid carbon and Neutro plus daily as per recommended dose.
Lights are on 6 hours a day but they are imo way too bright and you can't remove one tube 😡
Wondering if this is potassium deficiency on the Ludwigia Glandulosa and if so,how much extra K2SO4 to add.
Any help gratefully received 🙂

Old growth

Is that the old growth from when the plant was purchased ? Most of my stems shed the emersed leaves and they look like that. You can add a few pinches off k2so4 a couple of times a week see if it makes a difference.

Hi Tim yes it is the old growth from when it was purchased but I have also noticed a couple of pinholes in one crypt too.
I'll add a few pinches as you said to see if it does make a difference,many thanks 😀

Maybe it's owner deficiency? 😛

Old thread, i know.
I am curious if it worked though?
Did adding K2SO4 helped?
