I have a 28 gallon bowfront planted with Amazon Sword and Wysteria and am using pool filter sand for substrate. Both plant types used to thrive, but now the Wysteria has stopped growing and the Amazon Sword leaves are becoming transparent, paper thin, and a very light brown.
Is Seachem Flourish a suitable liquid fertilizer for these plants?
