I agree with Sally, no fertilizer yet. I have these planted both in the ground (inside my large greenhouse) and in containers. They get watered every day here in the late spring, summer and through September, which can be as hot as August here, 85-95 daily. We don;t start to cool down at all until October, and last October we set a record for the number of days that were 90 or above. Global warming at its finest.
You have nice specimens there, the petioles are highly variegated so you should gets a nicely variegated specimen from each.
Don;t overwater these inside with the lower light. We are actually able to grow these as pond and bog plants here, in summer, I have done that in the past, because trying to keep them adequately watered in the dog days of summer can be a challenge. Give some air movement too, a fan to circulate the air in their vicinity would be great. When it started active growth, puts out some new leaves and decides its ok, I would fertilize inside the house maybe once a month with a fertilizer that has low NPK ratio and is complete, has all the trace and micros. I use a liquid called DynaGro Foliage Pro. But there are many that would fit that same profile.
