> I think the exposed roots coming out of the holes are the problem. I would repot. > there's no need to repot, unless the tips of new growth are pushing against the rim of the pot and have no room to expand. I should slide it out of the pot and see if it's root-bound, I guess. But it was only repotted in the summer, I can't imagine it's full of roots after a winter (not the fastest growing time). > it's normal for old leaves on calathea to yellow in spring, before the new growth pushes out. I hope very much you are right. There is much more new growth being pushed out at the same time now than what was happening in the winter. Pruning old leaves is sort of an issue. I can't help but leave a dry stump. Maybe those will be easier to prune lower if the plant if in my hand with little soil on top (at repotting, in other words). Another Calathea (ornata, in the picture) has a couple leaves drying, but it's not bad. New leaves are also coming out of that one. > i assume you're feeding still. so continue. Yes. Considering increasing the fertilizer dose to all plants now that spring growth is happening. > don't move it away from light ;). it should be getting MORE light come spring, not less. Yeah, it was ok the whole winter under that light, so I think it should be fine. Robebuddy, are you reading all this as well? How is your Calathea doing?

Annamaria- relax and enjoy yourself. The blacktip on leaves is normal and just pop them off. Soon new ones will grow fine. Yellow leaves are usually just done and being replaced with new ones and the white sticky stuff is just some latex leaking out. Remember, there is no place for mother hens in the plumeria world. They tend to over kill every thing and just cause problems. As long as leaves are growing everything is on the right path. Find your zen moment and leave the plant to grow. Do get an inexpensive water meter from a nursery so you know that your pot is still moist and water when it approches dry. The rest is just relax and wait. Bill

they say that fluoride in water can cause leaf damage. I have several Calatheas, but the easier ones: Calathea princeps and vittata. and also Stromathe tricolor. they do get dried tips - but usually in winter and on old leaves. i don't sweat it. your humidity is probably good if you have a lot of them? and keeping them rather moist , not letting them dry up more then 1/3 of pot height? and light on feed with periodic flushing :))))? i looked at the first pic - it seems like you have tiny dots on yellow part - mites can cause that easily. and they are mite magnets ...even with high humidity.

What kind of pest? Why do you think that?
