i am no expert but I think itās a ph issue.
Had this recently and it was du to a ph swing. Maybe test your soils ph or try to see if you did anything different recently water wise. My problem was that I was ph ing the water after I added my microbes and I was doing it wrong as I learned that I have to fix my ec an ph to the desired number then add microbes and to not worry about the numbers showing after the microbial mass was added. After I realized that the bro zing stopped but the old affected leaves stayed the s
I was thinking it looks like spider mites as well but don't see any web on the plant. Would not hurt to give it a good once over. Soap and water spray will help. I'm thinking it could also be Calcium deficiency due to PH to high. Check your soil PH and if it's 7 get it down around 6.0 it looks like your growing in pots. If watering with rain water add 1 large green fertilizer spoon full of Apple cider vinegar to each watering can of water. This will bring the water from 7.0 to 6.0 and in turn the soil PH will slowly come down. Flood the pot with this several times like your flushing the pot. Then water with this mix from now on. As most off the shelf nutrients have a good balance there is likely enough calcium in the soil for the plant to be happy. Something is out of wack. If you get the PH in line the plant will go back to being happy.
So i have recently seen some webbing but last year we had a bit of a mite problem and they where everywhere but I think the webbing I saw was just a regular friendly spider we do have quite the gnat problem they came in our soil the Stonington blend platinum growers mix Everytime we get a bag they come with the soil so I figured they spider would help catch some of the gnats but I don't think we have mites nothing comes off when we shake the plant haven't done the paper test yet this year but it's just so bizarre I couldn't find anything online that would explain what it is so I'm going to take your advice and try the apple cider vinegar I usually water them then feed them with tiger bloom and bat guano and once a week add some
azos tea also gave a little nitrogen recently we also have a powdery mold issue so have been spraying them with lost coast every day this week but still seeing spots so thank you for your advice
