If you are using a good substrate with ferts in it I wouldn't start dosing heavy right away. The plants need to adjust to their new tank. Adjusting and rooting does require nutrients but you can overdo it at first and provide tons of nutrients for an algae explosion. It's difficult to avoid algae in a new tank so be ready for it it happens to us all. Keep the tank very clean and remove bad looking growth and melt right away to prevent any organic buildup. Best of luck!
