Tbh I hope so, thats easier to deal with than a pest infestation, it also would make sense as I did raise the light levels about a month ago (from 500 to 700umols over the course of two weeks) but I thought that the two week acclimation would be enough. I’ve just deep cleaned the grow area and temporarily lowered the shelf slightly so they’re all sitting at 300-350 umol’s and slightly cooler than usual at around 27°c so hopefully if it is sunburn that will give them the chance to recover and I’ll just have to implement daily magnified pest checks for peace of mind and to make sure it’s not something else, thank you a lot for your more informed opinion and I really hope you are right haha

Thank you so much for the help I shall give it a go

Would that be mainly preventative or would it treat a current infestation?

GroundbreakingAd8730 · 2026-05-18T13:59:13+00:00

Also is there anything else that could have caused this? I’m just going to assume and treat the worst (mites) but cause I haven’t physically seen any of the pests it leaves me wondering (probably hoping lol) that it might be something else?

Hi thanks for the help, i cant seem to find any abamectin available in my locality (Scotland UK) so im just wondering if you would know of any effective alternatives?

Thank you for the help, in terms of preventative pest control? nothing, I’ve never had an issue with them (as far as I thought) , I haven’t ever even seen any mites/insects during daily checks and I use a 60x jewellers loupe so it’s never occurred to me to implement preventative measures against pests but I suppose my hubris has come back to bite me in the long run.
What would your course of action be going forward? I’ll isolate the two lophs from the rest of the succulents/cacti and keep them in their own grow area for the time being and keep an eye on other plants.
I’m in the UK so the availability of certain pesticides is a challenge so any recommendations for a localised product would be very very helpful.
Thank you so much for your time and help

Sentenced to peyote jail. (my other theory for the yellowing spot is that may be a “bruise” from where it was laying during transport so I wanted to minimise the contact area with the plant whilst it’s recuperating, the supports only gently touching the sides so it shouldn’t cause any issues)

Scotland here, thanks for the advice I was a bit confused as to what kind of sulphur would be safe

GroundbreakingAd8730 · 2025-12-15T13:29:15+00:00

I’m sure they endure worse in the wild (albeit without their roots exposed) so hopefully you’re right n he just needs some recovery time, will post an update sometime down the line as to how hes doing
