Plants and brown paches

in my tank I have no fish yet just live plants, but I noticed some of my plants leaves are starting to turn brown, I do put liquid fertilizer and leave light in tank on for about 8hrs to 12 hrs a day. and put flake food in every once and awhile. what could be the problem

 

what are you using to cycle the tank?

flake food and freeze dried shrimp every 3 days, as I do not plan to add fish for at leaset 2-4 weeks, I did check water for Ph nitrates ext.. all levels good

 

the brown patches are getting lager please does anyone have any advise or something
better then liquid plant food, should I try pellet form.

 

I've noticed that sometimes new tanks will develop a brown algae problem. Mine has always vanished on its own after a few weeks.

 

The leaves seem to be dying - are they getting enough light? Can you give us your tank size, the wattage of your light, and the name of the plant?

 

Do you happen to remember back when you first got the plants...would they stand up fine when they were out of water?

 

the plants I have
wattage they are bulbs that came with tank kit it is 10 gallons
and tank is 35 feet from window

1 Java Fern
1 Anacharis
1 Anubias Frazeri
1 Aglaonema ( Silver Queen )
1 Rotala macrandra-narrow

 

Aglaonema is not an aquatic plant, will doe in your tank.

Can't really tell what the plant in the picture is.

I purchased Aglaonema about 3 weeks ago at petcetera .

 

My java fern is doing the worst

 

What are the water parameters? Ammonia, Nitrites and Nitrates?
Frequently the pet stores will have non-aquatic plants. That's why it's best to know what your buying fisrt
