Hi guys, so I set a new tank up 8 days ago and all is going well apart from the rotala at the back of the tank looks pale on some leaves and dark green almost algae like on others.

Dark start method used for two weeks prior to planting
45p
Co2
Temp 22c
Biomaster filter matrix packed
ADA ver 2
ADA power sand
Root tabs
Ferts - Sechem advance 2 mls daily , then after two weeks will switch to Sechem lean dosing
Plants are all from one 2 grow cups
Twinstar LED V3 Aquarium Light 450SM

Not sure if it’s a deficiency but surely not this early on ??

Neither am I but iron deficiency is definitely possible.
It's good that you provided some info about your tank, but water parameters are missing. If your water is hard/alkaline/basic, then iron will be your permanent problem. Strong chelates may be required.

You do know that Seachem Fluorish Advance is NOT a plant fertiliser?

It’s sold as a Growth enhancer for young plants, I was just following Geordie scapers advice with dosing that for the first 10 to 14 days then after will kick ferts in .

Amonia , nitrite and nitrate are all 0
I am unsure about what hardness, how do I test that??
When you say chelates do you mean dose Sechem iron ??
 
Forgot to say my light schedual is 8 hours
Co2 on 7am
9am 50%
12.00 70%
2pm 65%
4pm 55% co2 off
5pm 45%

You can search your areas water report online and that should give you general idea regards how soft/hard the water is in your neck of the woods.

No. I mean strong iron chelates. Google for iron-DTPA, iron-EDDHMA, etc. These are compounds widely used in agriculture and our hobby to make iron accessible to plants even in unfavourable conditions - which is your water.

<"Seachem - Flourish Advance">. There is a word for Seachem and <"their advertising">, and it isn't necessarily <"very complementary">.

Seachem <"Seachem - Flourish Iron"> is <"ferrous gluconate based">, you need a chelator more <"suitable for hard water">*. Edit what @_Maq_ says.
You may also struggle with iron (Fe) availability using <"Seachem Iron">, it is <"ferrous (FeII) gluconate"> (C12H22FeO14) based. Seachem will <"spin you a line"> about this being "more plant available" but in <"hard, alkaline water"> the opposite is true.

What @John q says, use the values from your water company, they have an <"analytical lab.">

You won't have no nitrate (NO3-), but nitrate is one of the nutrients that is difficult to test for <"Measurement of Nitrate with a Spectrophotometer">.

Rotala rotundifolia features in quite a lot of iron (Fe) threads, because it is a plant that shows <"any deficiency in iron availability"> pretty quickly. Have a look at <"Should i start to fertilize?">

Its just a root hormone. You can buy a large pack of similar powder from your garden centre for a few dollars/quid.

During the first ten to fourteen days after application, Flourish Advance™ works to stimulate root growth beneath the surface. After this initial induction period, significantly enhanced growth in the leaves and stems of the plants will occur.

The seachem marketing text is brilliant. If you read it carefully, you will see that the only claimed effect is stimulation of root growth beneath the surface. The promise of significantly enhanced growth in the leaves and stems have nothing to do with the phytohormone but is just an assumption that a plant with a developed root system will grow faster than one without.

For terrestrial plants, you apply the phytohormone directly to the root area. Here you add to the water column resulting in massive dilution and I have no idea how the phytohormone gets under the substrate to reach the root area/root tips.

Ok I’ll start dosing ferts tomorow.
Can anyone point me in the right direction for the DTPA, iron-EDDHMA??

Does this stuff have iron in it or does it just allow for iron to be consumed better in circumstances when water is hard ??

Phytohormones are a group of chemicals influencing growth, and I know that foliar application of at least some of them is in use. They seem to be mobile in phloem, then.
But generally, my stance towards Seachem is similar. I quite admit that several of their products may be good, but the way they communicate with customer is insincere.

They contain chelated iron (Fe), but it is a bit of both. The issue is keeping iron ions (Fe++(+)) in solution and plant available.

Have a look at <"https://www.ukaps.org/forum/threads/jungle-flex-57l.64672/#post-722013">.

There are three major "problems" with iron and plants:

I admire <"them in some ways">, but you could only craft your advertising that carefully if your aim was to <"mislead and confuse">.

Solid info above.
Were these plants in-vitro or potted? This is common in new setups, more so w/ in-vitro. FE, I have transferred tons of stems of rotala from tank to tank, new or established. This is fairly typical in my experience.

Plants seem to be growing healthy shoots now .
Have started lean dosing
