New growth and nodes dying, but fan leaves are fine

Discussion in 'Sick Plants and Problems' started by EAPaaron19, Oct 17, 2022.

  1. I purchased these large vegging plants from somebody that are sitting in my quarantine room and all 6 of them are now doing this 5 days later of having them in my possession. They did have some spider mites in which I am treating them.

    The nodes and a new growth everywhere are literally rotting away and necrosis. The fan leaves are just fine though. I have never seen anything like this. Some of the pots are dry some of the pots are wet and watered so there's definitely differences in how they were treated before I got them.

    I am trying to diagnose what is going on here?

  3. How are you treating these plants for spider mites. It looks almost like they were sprayed with a heavy dose of insecticide or perhaps it wasn't agitated when you were spraying it.

  4. Naw, they were sprayed with lost coast therapy. That wouldn't have harmed the plants. I use this stuff all the time for years. These plants just didn't look quite right when I got them but now they're basically necrosis on all the new growth
     
  5. Does the soil smell anaerobic? Like rotten eggs. You stated they looked fine before you got them and only after you took possession of them did they begin to show issues. Are there any variables that have drastically changed. I've never used Lost coast therapy. So, I wouldn't feel comfortable commenting on that. I did however accidentally spray a clone with a bleach mix I use to sanitize my tent between grows and my plant looked very similar to yours. All the new growth was dead or dying the next day. The leaves died a few days later. The plant was dead within 5 days. I have since labeled all my common sprayers.

    The quarantine room does have a rotten smell to it. I assumed that it was because the previous grower sprayed sulfur on them. The plants didn't look like they were good healthy plants when I got them, but they wernt dying at the time

  7. if they are in buckets, just drill a single hole in the side bottom and take a smell , the rotten egg smell is what i think you will find there ,

  8. They looked like fabric pots from the picture @old shol4evr. That's why I didn't think root issues. Unless what looks like perlite on top of the soil is the only aeration that it had. Those pots are really hard to over water unless you run a really muddy soil. Or they were in a flooded plant saucer or tray.

  9. thats why i asked, my daughter in law uses them bags, why i dont know, she will only water them about once a week in this hot texas sun right , now the root ball does twist up in there , she uses that kellog soil when she get the spring bug, i have taken those plants from the bags and they do twist up.
    sitting in a tray ,maybe and probally , but even so the root system doesnt just stop at the bottom in them bags, anyway again my sugest ,hope the op figures it out , myself i wouldnt take that chance in my flower room , usually taking someone else plants has a reason , more often than not is because they already ran into problem and didnt want to deal with it

  10. As hearty as I've found my plants to be, I would recommend completely repotting them - wash away all old soil and replace with your mix.

  11. The only other time I've seen something like this was with a crab apple tree I had for years. Healthy as could be, then died very suddenly. It was wire worms that attacked the base of the trunk at the top of the root ball. They killed the tree within a few months.

  12. With the whole plant affected it looks root related and like Tim suggested smell the soil. Dig a small hole and sniff the soil from the deepest part. The only time I had a plant look like that it soon was beyond saving and the soil stunk like rotten eggs (Sulfur) when I dumped it out.

    The other possibilities are Root Aphids then fungal or pathogen.
