I setup a 300 litre tank a week ago and from the off planted around 15 different species of plants. I used Tropica Soil as my main substrate with JBL Aquabasis+ underneath it. I seeded the filter with media from a friends tank, and initially dosed ammonia up to 1ppm, and after 1 week my current readings are:

Ammonia 0.2
Nitrite 1.0
Nitrate 40

I am wondering when I need to start dosing for my plants? I have Easylife Fertilizer and Easy Carbo ready to use. I wish the tank to be low/medium tech, so I dont want the plants growing crazy fast, but at the same time I want them to be healthy. I have mostly easy plants such as Anubias, Java Fern, Amazon Swords, Crypts, as well as some red Ludwigia, however soon I am going to buy some S. Repens to hopefully use as a carpet plant.
