Plant problems - advice please!

[BucketOfFrogs]

I have several tanks of varying sizes; the plants in my smaller betta tanks do fine, but my bigger tanks seem to be suffering. My java ferns are disappearing - used to be lush but now pin holes, brown leaves etc. Anubias also seeing yellow & brown leaves. Very little new growth on ferns or anubias. Nymphaea developed holes in leaves too.

Low tech, sand substrate, tap water is hard but currently transitioning the bigger tanks over to the same tap / RO mix I use for betta, so will be softer over time. Tanks usually run quite high Nitrate levels and have water changes weekly - about 30% on the 300l and about 50% on the 110l.

Things I have to hand: flourish root tabs (currently used in the 300l tank round the amazon swords, nymphaea etc), tropica root capsules (just put some in my 110l yesterday, with new plants), TNC Complete (used to dose both big tanks weekly as per bottle, but didn't seem to help), Aquadip Ferro, Aquadip Fosfo and Aquadip Potassium.

Could anyone please offer some advice on the best plan to get my plants back to life please?

This is just what l would do, stick to TNC Complete it has everything your plants should need, l would if possible do daily waterchanges for now, cut off any dead bad leafs, add fast growing stems, some of these plants don't require too high lighting ferns and anubias, some floating plants will be beneficial. Just give it time ,maybe look at cutting with rainwater later

Hi all,
Welcome to UKAPS.

My java ferns are disappearing - used to be lush but now pin holes, brown leaves etc. Anubias also seeing yellow & brown leaves. Very little new growth on ferns or anubias. Nymphaea developed holes in leaves too.

It looks to be a nutrient deficiency. Plant growth is like a <"car assembly line">, you need all the "components" (essential plant nutrients) before you get a "car" (plant growth).

If you look at this image:

You can see that it is the older leaves on the Echinodorus bleheri <"https://tropica.com/en/plants/plantdetails/4512/4512"> are pale green and also have <"interveinal chlorosis">. This means that <"Liebig's limiting nutrient"> is a nutrient that is mobile within the plant. Have a look at <"What is the “Duckweed Index” all about?"> and subsequent posts in that thread.

Could anyone please offer some advice on the best plan to get my plants back to life please?

This is just what l would do, stick to TNC Complete it has everything your plants should need

@PARAGUAY's advice, the only thing I'd add would be some <"Epsom Salts"> (MgSO4.7H2O), cheap to buy and 10% magnesium (Mg).

If the new leaves are also yellow and chlorotic? Then you have an <"iron (Fe) deficiency as well">. Iron isn't mobile within the plant, so deficiencies effect new foliage.
In hard water you may need <"another chelator for iron">, dependent on the formulation of Aquadip Ferro <"AQUADIP Ferro - 500 ml - AQUADIP">.
