Hey mate.
That may be the worst of them. But by the looks of your pic the one to the left looks very similar.
I'm not suggesting anything, but, I know a guy who's plants always look similar, he virtually has a peak every two or three days. He has a multitude of problems and has had thrips and mites but not generally, he just doesn't dial anything in.
Still produces, and some is great quality but you get out what you put in.
The book Marijuana horticulture by Jorge Cervantes will help you any many others. Can be downloaded.
This info may help.
Size of room? Type of media? How many and what lights? Breeder of said plant? Which Nutrients? EC? PH? Fans ( extraction and circulation)? How often do you change nutes? What's the watering schedule? What type of nutes? RO water or tap? Temp high, low and average? Humidity high, low, average? How many days in what stage? Are you trying to scrog? Do you have external air coming in at what volume Lt per min? How long did they veg? Are they seeds or cuttings?
Cheers
