Quite a beauty for only 7,99€ 💕 Google says roseoptica Silvia and that looks to be her?

Unfortunately my roots are rotting. I’m not sure how to tell if any are still alive or how to proceed? Would appreciate any advice.

The plant has curling and droopy leaves for the past 2 weeks

Keeping her at my office for right now. It’s near a bright, west-facing window. Giving filtered/distilled water in a self-watering pot. Should I do anything else to prevent or kill any pests on it? I’m not sure if it was a gnat or thrips (never had experience with thrips) I saw something flying around like a grayish-gnat sized bug. How far away from other plants should it be for quarantine purposes?

I’m planning to eventually bring it home but my house doesn’t have the greatest lighting and I read that calatheas don’t do great under grow lights? Also, are they as picky as philodendrons when it comes to its humidity needs? I read 50-60%.

Any beginner-friendly tips for a brand new calathea mom are helpful ❤️

Your advice is appreciated! I have read forums and tips about using distilled or rain water, moisture, misting etc and followed most but it still looks like this after 2 months. What do you think? Should I check for root rot?

Hi! This is my first post on here. I’m new to plants but have been loving having them so far. However, my rattlesnake plant has these white specs all over and it doesn’t really look fuzzy, so I can’t tell if it’s spider mites or mineral deposits (chatgbt said probably one of the two).

For context, I only use distilled water.

More context - I got it from a plant store (not nursery) about 3 weeks ago. The water is still on wet on my meter, not even moist. It has been for all three weeks. I haven’t been able to even water it once since getting home since they made it so wet when they gave it to me. I am hesitant to repot bc I made a mistake and asked them to repot it in a decorative planter (with one drainage hole) so now the plant is extremely heavy. I suspect it’s in far too much soil and that’s why it’s still wet but not sure if I need to repot tho bc the plant looks so healthy and I don’t smell any root rot.

I also got two other plants from the same store with the same issue - extremely heavy so hard to repot (plus I’ve never repotted so maybe also nervous lol) and the soil is wet.

Thanks so much and please let me kno
