Red Flame Sword Color
Hi Everyone! I've been been referencing this site for a while now and thought I should finally make an account. Turns out I've already got a problem that I need some help solving.
I got 2 red flame swords about two months ago. When I first got them, they were green but some of the leaves soon turned red. A few weeks ago, some of the leaves started turning a deep red and almost brown color (I've attached a photo for reference). I started using injected CO2 about a week ago the deepening of the color seems to have accelerated since then. The leaves have also started becoming very thin and fragile.
Is this normal for this plant? If not, any ideas what might be going on?
I use liquid ferts and root tabs in my setup with a Finnex light system that has been running through its pre-programmed 24 hr cycle. As mentioned, I started using injected CO2 about a week ago but was using API's CO2 Booster beforehand.
