Hey - totally new to this - tank has been running for 10 days - ph is 7.4, ammonia is .5ppm, no nitrate or nitrite yet. Water is treated with Stability (stuck one fish in 4 days ago), Prime and Flourish excel according to directions. Using Tropica planting powder and have 23watts of led lighting for 10 gallons. Some of my plant leaves are starting to yellow and thin and the new growth looks similar. I'm also using root tabs (starting today). Am I doing something wrong? The Monte Carlo is doing great sending runners - that's the medium difficulty plant - all the easy plants have yellowing leaves. Moss is doing well too. Is it too much light? Do I need more micro-nutrients - specifically iron? Thanks you for your help!
