Septoria disease?

Hello mate, in my experience this signs are the bites of thrips or at most whitefly. You could use the coloured traps and the neem's oil with potassium soap to protect your plants. Good luck!

goodnight. The name of the pest that is attacking your plant is spider mite. it is located at the bottom of the plant, and can be treated with neem oil. foliar watering in the sense of washing them can be very beneficial to avoid them, ventilation and good cleaning; It is worth mentioning that mites are mites, and they do not die with bactericides, only with acaricides. Follow my diary for more information, and you can count on me whenever you need.

THRIPS!

possibly spidermites, look under the leaves if you see any reddish brown spots that you can wipe over and squash, it's them.

i only know this as a spint infection. you must wash your plant with a solution of soap and vinegar google it.

more likely some pests suckling your leaves.
