Care/feeding Plants in Discus tank
My question is: can and should plants be given plant feed in a discus tank? Since discus need such clean water, can adding plant food hurt them? Can plant food sticks be used in the sand and/or can liquid plant food be added as well? Could peat be added to the sand instead?
Also, does plant food help algae, too?

You are safe using ferts and/or substrate fertilization in a Discus tank. I use the estimated index fertilizing method with CO2. They only time I had problems was a few months ago when my ph probe failed and I almost killed my fish via CO2 poisoning.
As long as you make sure the water quality stays good, you shouldn't have any problems.
As far as algae, you should definitely look into the different fertilizing methods. If you are going very low tech, then good substrate fertilizers work well for many root-feeding plants like swords and they don't promote algae growth. If you are going with a high light setup, you usually need to use CO2 injection and a more continuous fertilizing method like the EI method. Algae can be a problem, but as long as you keep your water parameters, and the light-fert-co2 amounts in balance it wont get out of control.
In any case it's all about balance. Any time you have algae outbreaks it means that some parameter is out of whack. This could be too much light, too little light, not enough CO2, or nutrients out of balance. Fix the unbalanced parameter and the algae goes away. The hard part is usually figuring out what out of spec.

Care and feeding plants
Thank you! May consider a low tech CO2 system
