Thanks for the advice. Temps have come down in the last week or so and things are doing much better. Two of the three turned out to be dudes and have been banished outdoors. The remaining Blue Mystic girl has tripled in size from the photo above. I couldn't get the photo loader to cooperate and upload. There's plenty of good vigorous root growth now, it's beginning the stretch process and the solution is not sliming things like it was. Thanks for the pointers all.
