Leaf issue

Coud be calcium deficiency which leads directly to mag deficiency at some point. try and feed her calmag for a periode of time, and see if it stops😊 Best of luck mate .

Yeah no viruses lol. If you want to do some trouble shooting next time you water test the "run off" ( the water that comes out of the bottom of the pot ) to see if the PH is in the correct range. Also test PPM to see if in correct range. If all is in range then you could use come calcium and magnesium. But most of the time the plants will show a cal mag deficiency when the PH is out of range. Also can develop a rusty color if PPM is too high.. ✌️

Whoa—- not tobacco mosaic at all. Plant looks good. Could be a little ph fluctuations or the stereotypical cal mag. I would just feed some straight water for a bit and get back at it. Sometimes each plant feeds differently🚀

Hola bro ! Buena tarde ..la verdad no se ve tan terrible...no parece que fuese alguna plaga o simillar , si no me equivoco es el "virus del mosaico del tabaco" ... sólo debe prevenir con asegurar que tus implementos de uso ( tijeras guantes manos etc ) estén desinfectados ...te dejo una reseña de los grandes de fatsbuds hablando de esto !
