OK, the sand is fine and parameters are good. Your problem is the plants but not hard to fix. Swords are heavy root feeders so need root tabs with good iron in them. They also light med to high light so make sure the are under the brightest of your 2 bulbs.
Java fern is a low light plants so you can put it somewhere in tank where light is lower. It will need water ferts like flourish.
Bushy plants light med to high light. Your crypts love low light. Anubias will also do ok in lower light.
Ok this might sound silly but how long are your lights on? If on over 8 hours cut back to 8 or 6 for a week or two. That should get rid of algea.
