hi,
congrats on the spiders!
About Marantas, the "black on them" is just a darker green so it is good. I don't know what caused the holes but I wouldn't cut the tips off. The leaves look a bit dry on that pic. Are they potted in pebbles or is that only topping?

You need to find the right spot for a prayer plant. They don't like too much or too little light. Their colors are best when they get the ideal amount of light.

Thank you for the reply MsGreen
There's rocks on top and bottom. There dirt is also a little to wet atm as they were out in the rain. I must look like a crazy person when it rains as I run all my plants outside and buckets to catch the rain. Nothing but rain water for my plants now just don't know about when winter comes. :/
Sadly before that though I left them hanging out on the porch as I didn't know they would dislike the light. Spider plants love when I let them hang out on the porch but not the prayer plants so I'll just take them out for rain as long as it stays warm. The picture was taken the night after I though they looked a little sad (folded up wrong and laying on each other in the middle of the pot) and moved them inside. We had just saw them at the store and brought them home and repotted them a few days before that. The bigger one really needed the new pot. Poor guys I didn't mean to hurt them. There inside now getting indirect sun. I'm not sure if its to little or not yet but they are closing at night and open in the morning when I wake up. I'll just have to watch how they do.
I could give them a good misting if you think they would like it. I wasn't sure if I should do so as they just got rained on a few days ago.

Here's 2 more pictures I just took. I had to move them out of the window for the pictures as the sun was messing up how my pictures turned out.
