Howdy, was just wondering if anybody could help me out with my amazon sword. I've been watching one of the plants, and it started to get these red spots on it. I think it might be snails, but not quite sure.
Usually those kinda spots result either bcoz lack of ferrus or a decay caused by water quality.
Add some ferrus based liquid fertlizers and monitor the water quality regularly. I got mine growing tremindously with a periodic iron feeding..
Good luck..
