I have 29 Gallon, 100 wattsof light, laterite/tiny gravel, DIY CO2, jobes Plant spikes under the rooted plants, and liqid fertilizer (forget what type) as directed. I planted two plants of watersprite, and watched them turn brown over a couple of weeks. I moved them to get a better spot in the aquarium and the roots looked like they rotted! What did I do wrong? Can they come back? Im worried that they are indicating what is going to happen to other plants, like they are sensitive. My other plants seem to be growing just fine though.
