Problems with Stem & High-Growth Plants (Photos)
I am hoping someone can look at my attached photos and let me know what I need to improve. I am having a very difficult time getting any of my higher growth plants to stay healthy and maintain existing leaves. They grow well, but older leaves quickly die. Slower plants like Anubias and Bucephalandra appear fine. The plants I am having issues with are:
Amazon Sword: Growing well, but leaves tend to deteriorate once they mature (picture attached)
Ludwigia & Water Wisteria: Both are growing very quickly but within a week the leaves appear to develop dark lines then die off. My plants can not maintain more then two to three bunches of leaves as a time and I end up having a long stem with sad looking leaves up top. (picture attached)
Anacharis: Grows very well but leaves quickly turn brown after a few days and then it gets attacked by diatoms and literally dissolves.
My tank is 5G and I perform 50% water changes once a week. I dose Nilocg Thrive once a week as directed and Excel once a day as directed. I do not use CO2. I have a Finnex 24/7 which I run at full power for three hours and the tank receives about 2-3 hours of moderate indirect sunlight. I have very mild green spot algae on my glass but not enough to really notice.
I believe my issues plant issues are caused by a nutrient issue, but I can not narrow it down. The deficiency charts I have looked at on line do not describe the issue I have with the Ludwigia and Water Wisteria. I have tried dosing Thrive more times during the week to up the nutrients, but this has resulted in my Nitrate's measuring between 80 - 120, so I am guessing I do not have a Nitrate issue. Normally Nitrates in my tank are at 40 and Ammonia/Nitrite are at zero. Water is on the harder side with a 7.5 - 8 PH.
Can anyone with good knowledge here point me to the right direction.
