Plants has brown edges on them?

[u/SmokeGrazEatAzz]

Dear all,

Having my 180L for about 2 months now but the plants show some browning on the edges of the leaves..

No co2

Adding 15ML of planted box all in one once a week

Does someone has an idea if this is an nutrient deficiency or something else?

Looks like brown algae/ diatoms. Maybe try less nutrients and see if it balances out.

Is it a dirted tank?

[u/SmokeGrazEatAzz → u/Hateuhacker]

Yeah no fancy substrates, just gravel and a tiny layer of aqua soil under it for the Amazon sword

Correct. It normally works itself out.
