Could someone please tell me why my plants have brown spots, dots on their leaves?
In the first photo, you can see that the newly grown leaves are light green (healthy), but the old ones are covered with brown spots.
In the second picture, you can see the plants (dont know its name) are pink on the top (healthy), but the leaves below have either fallen off or about to.
Is this because of a lack of iron, potassium, CO2?
A little bit about my tank...
- 29 gallon
- one 65w Power Compact in the back, one 40w regular flourescent in the front (the light that comes with 55gallon tank), 10hr/day
- DIY CO2, 2 liter, air stone at the end to decrease the bubble size, then are taken in by the power head and distributed throughout the tank
- water condition: 7.4pH, 77 degree F.
- 25% water change every week or twice a week if I have time
- fertilizers I use are shown below. I added 20mL of the "leaf zone" once a week and placed the tabs once every two weeks at where the rooted plants are (half a tablet to one, depending on the plant size)
