insufficient light reaching the base?
ImageUploadedByTapatalk1385482687.715284.jpg
Hi,
I noticed stalk of plants are turning brown.
It's a new setup tank,approximately 1week. Please find parameter below.
Substrate : Ada Amazonia
Light: green element 18w (3w x 6)
Filter: internal
Co2: 1bps
Fertilizer: none
What could be possible cause? Apologies for poor photo quality.
Thank you

how are the leaves at the browning stem area?
how are the leaves and stems of the surrounding plants at the same height.
Likely to be issue with light penetration.
I am balding but i am still young!
Hi ,
Thank you for the reply. I am not sure if it is lighting as my tank is only 30cm high (30cm cube to be exact) and I am using Green Element(Plant) 18W LED. So I believe lighting should not be issue. May be I am wrong.
The problem plant is the first batch to introduce to tank and the top leaves look fine. I will continue to monitor the surrounding plant, those are only introduced 2 days ago. There are leaflets growing on the brown area as well. Is this consider rotting?
Hope the new photos are more useful
Thank you
cut the healthy top, remove the rotten bottom and replant the top.
Is the brown portion soft like rotting tissue? if its soft, time to cut and replant like what shadow mentioned.
I am balding but i am still young!
Thank you. I will check tonight.
It's the first time I am using LED, is the current lighting sufficient to grow most plant?
I have base fertiliser in the tank, when do I need to start dosing liquid fertiliser? If so, do I start with N,P and K right away?
I have no experience with 18W Green Evo, but i have read forum feedback on this LED. you might want to search on the forum for the feedback.Originally Posted by fookie
As for ferting the water column, it depends on the flora in the tank. any water column feeders? if yes, then you need to put liquid ferts into the tank.
If there is none (all root feeders) then you might want to dose once in a while to extend the life of the substrate. I personally do not fert my tank with root feeders only.

May I know the possible cause so that I can avoid this in the future?

If it is rot, it can be simply handling issue such as accidentally bend the stem or press the stem to much and damage it
Sorry for the confusion. The Plant is Ammania sp. ‘Bonsai’ which under highlight the stem will be red colour.
I remove the plant and found that the brown portion is firm and with roots.

Those with brown stems were probably abit damaged during cleaning and planting so not doing so well... i notice the ones next to them look okay, so its not a light issue.
Like shadow mentioned, when they grow taller, just cut the healthy top section, remove the lower section and replant the tops. You'll need to do this periodically with stem plants anyways, as the older bottom sections will usually degrade over time.
Do you mean that it might still rot even if root system is establishing?

The affected stem sections might still rot or just be abit weaker... stem plants can be easily maintained by regularly cutting away weak parts and re-planting, so its actually not a big issue.
Btw, i was looking up some images on google on Ammania sp. Bonsai and some photos show them with reddish/brownish stems too, so maybe it could just be a normal color variation in the stems due to different tank conditions and lighting.
