Anubius getting brownish edges

[Martin in Holland]

Lately my Anubius nana and petit got some brownish leave edges, in the beginning I blamed it to my bleach treatment, but this is already been done 2 months ago.....any ideas how what this could cause?

Light 7 hours 3 floodlight 20W LED
PPS pro ferts
CO2 (1 pH drop before lights come on and staying stable)
tank: 120X45X55
2 filters, both 1500 l/h

Could be Nitrogen deficiency.

Hi Martin, I think you are right it could of been the bleach treatment. I did the same thing and the leaves went brown and died off 🙁 Cut off the affected leaf new growth will soon appear 😉

Me too Martin i think it still is the bleach damage.. Anubias not only is a resilient slow grower but also a slow succumber.. It looks very much the same as my nana which i possioned with to much spot carbo once.. Took a while but i killed a few leaves too.. 🙂 🙁

Tho never managed to kill one with peroxide, this they take very well.. And blackouts, man that's something you realy have to try.. After 4 days blackout took off the cover and saw nothing but new anubias leaves unbelievable how this plant triggers new growt in the dark. And the whole plant spot on clean. Hence it's name, the egyptian god of the underworld. Only to see that again and have a laugh i would like to blackout again.. After doing a search about it, Tom Barr reported the same observation..

Probably the bleach caused some buds to get effected too and they are showing this now....bummer, but it will grow back, just takes a while longer.
Thanks for your replies.
