The liquid fertilizer I mentioned previously is advisable. For swords, substrate tabs like Flourish Tabs are also good, but with or without these the liquid is still necessary because some nutrients are taken up via the leaves and substrate fertilizers don't provide this.
This will also work against algae, as the plants will use the nutrients and light to out-compete. I can see evidence in the leaves in the earlier photo of nutrient deficiency, so this should help.
