I got 1 amazon sword in ym 55 and it is doing great, all the original leaves melted as expected, and regrew more than double at this point. thing is i have noticed the new leaves look very different. the original leaves were more round and brighter in color then the new leaves. the new leaves are alot thinner and longer and alot darker in color. it's still a beautiful plant but was wondering if anyone knows what may have caused this?
