hello, today i just switched on the lights noticed that my Rotala rotundifolia was showing signs of deficiency in the form of scrunched/curled up up leaves
i have been dosing tropica specialised fertilizer at 0.6ml a day is this maybe to little? the tank has been set up for 1 week only. yesterday the stem were trimmed and some replanted. not all stems have this issue but some do
aquarium:
16litre
Co2 is high and so is Flow .
substrate is aqua soil amazonia
Using Ro Water
TDS:130ppm
GH:4
KH:2
today i increased the dosage to 1ml

i change 50% give or take every other day, i know they say it should be everyday in the first week but i have been slighty lazy with it, you think that could be the reason ? high ammonia levels? i have not tested my ammonia levels

Hi.. ada amazonia is known to leach out ammonia but plants thrive in that environment. This plant with stunted deformed new leaves looks to be located in a corner. Think it's not receiving much co2 there. I had exact symptoms in one corner of my 100 gallons with limnophila aromatica and ammania. Some wise people said it was co2 but I didn't listen as I thought my co2 distribution was top notch. I tried everything from reducing ferts to avoid "toxicity" to finally overdosing to eliminate any limiting factor. Finally I redistributed my flow of co2 directing it into that corner and u know what.. no more stunted leaves. U may pump in enormous amts of co2 but believe me.. its distribution that s key. I learnt it the hard way. If u post a whole tank pic and also pics to explain how u r distributing ur co2 then perhaps we can try and solve this issue. The only other things that can cause misshapen new leaves r calcium or iron deficiency. But go to that only if co2 correction doesn't work as they both r less likely to be the cause.

Very similar in dosing urea to provide NH4, too much and you're in trouble with algae.
Most new tanks are also started with a minimum of plants, it would seem using Aquasoil it would be best with a very dense first planting.

@h1234 are those emersed stems transitioning to submerged in the pic.
Looks like bottom leaves are very round, then a few nodes taper out, and then the crunched up leaves appear.

hello. il post a full tank shot soon, that being said I'm fairly certain the issue is not related to co2, reason being is that first my drop checker is in that area of the tank and the rotala does visibly pearl throughout , filtration is strong, using a eheim 2211 and the stems do visibly sway, that being said how long should a drop check take to turn green if switching the co2 on 2 hours prior to lights?

those specific leaves are taking a while to transition to there submerged state, and again not all the leaves are crunched only on 2 stems from about 10-12 stems.
that surely is a good sign? il post photos of my othrer stems later today

Tank is only a week old, new plant, looks like it was grown emergent.
Likely new adaption.

New tanks rarely have the CO2 dialed in nicely also.
