Is this a fungus on my Hoya leaves? This vine is new from this summer and it’s only on this vine. The other two are fine. Help please

New leaf Issue (Calathea Beauty Star): I have a new leaf growing in on my Calathea Beauty Star that has some odd damage on the tip. No signs of pests or disease that I see. Previously, in early October I had washed the leaves (one time) with a water/alcohol/soap solution and then spots appeared on the leaves, I think caused by sun damage + alcohol left by the spray. I am unsure if this is related to this, but the new leaf would not have been sprayed. Any ideas what could be the cause? Maybe just mechanical damage?

Went on a one week vacation and when I returned 3 of the leaves if my monsters are browning at the edges, is this a sign of thirps? Or another pest?

Hi friends, my hanging monstera is yellowing on the leaves 🥺 I’m assuming this isn’t good, what can I do?? I haven’t repot it in probably two years, it’s hanging near a window. This happened quickly

Just a little bit of a warning. I was watching one of my favorite plant guys on YouTube. Can’t remember which one. But they said they were using a mix of compost, cocoa coir and perlite as their new potting medium. I tried it. None of the plants I used it on liked it. Lost a few. I’ve gone back to my basic potting soil with additional perlite, amount depending on the plant. Sigh. Probably should stop experimenting. Lol. 🤦🏼‍♀️

I’m in fungus gnat hell - so frustrated and about ready to cry or toss out my plants or both! I have a collection of about 50 plants - about which 13 have an ongoing infestation of various severities since the past 2 months. Every plants has a sticky stix and I check them daily to do a “trap” count. I have tried combinations of quarantines, top and bottom watering with BTi tea (have used for about 4-5 weeks now), hydrogen peroxide flushes, repotting, diamateous earth, cinnamon, closing up the bottom holes with coffee filters and elastics, apple cider vinegar traps, and drying out the plants as much as I can before they’re sad. I don’t see a big reduction in gnats; they’re still around when I poke at the soil. I looked at one of the peace lilies that I did a hydrogen peroxide flush on LAST NIGHT and now there are at least 4 new gnats caught in the sticky stix trap. ***Do both BTi and a hydrogen peroxide flush render the soil inhospitable for as long as the soil is wet or do the effects wear off the next day? I don’t understand why there are new gnats on this plant. Am I causing a problem because now I have a really nice moist plant available to the gnats again? ***How long does it take to eradicate this pest using BTi tea?? Is there any hope for me?

Hellllp I got my Alocasia (Dracula) about three days ago and I’m starting to notice that the flowers that are supposed to be blooming are starting to burn. Today was the first day I put her into a sunny spot in my living room. She only got about three hours of sun, because I didn’t want to overwhelm her. And now there’s a scab on her leaf. Also, I’ve heard a lot about cutting off the flowers , is that something you think I should do. This is also my first time having a plant like this.

Help! I have this oyster plant that has been steadily losing the lower leaves. They’ve been turning brown at the tips and then sort of wilting inwards. I’ve pruned it, repotted it, and it lives in a room that maintains 60 to 70% humidity.

Ok so, I've this this Hoya for a bit and she's been repotted a couple times. Not too long ago, she had one new leaf come in (the very top one). The leaves closer to the top feel alive (if that makes sense) and have spots. Meanwhile, the lower leaves feel thin and kinda papery. Why? And what should I do? Also, ignore the dust- I need to give my plants a dusting- I just keep putting it off...

I got this yucca plant a few weeks ago and started noticing the tips of the plant are starting to turn brown and get all dry. Any recommendations on how to help this plant?

Just got this beautiful Bird of Paradise plant, and after 2 days, I noticed small brown/black dots. Any ideas on what it could be, and how can I treat it? Please help, I'm desperate!!!

Can’t tell if this is a pest or not. Small white dots on the bottom of my leaves. Seems granular, doesn’t appear to be moving.. there’s this small possibility it’s salt because I have this thing called a bug-a-salt.. but yeh anyone able to positively identify?

Mealy bugs — what’s the effective way to destroy and prevent besides a flamethrower? I’ve lost several legacy pothos plants to those buggers and nothing seems to work… I’ve tried neem oil, rubbing alcohol / water mixture, spraying with water and repotting up to three times and isolating in different parts of the house. They always come back with a vengeance! Sincerely, At my wits end

Just got this prayer plant from the clearance section, any tips on how to save it? And should i put the vines together or leave them like this? And is the drooping normal?
