Strange leaves

@hashy is right TMV and the plant is having issues triying to resist, there is no cure or treatment, some recent studies showed that essential oils based on terpenoids like a-pinene d-limonene... could've some grade of inibition by turning on defence signaling and they also minimize the infectivity because they have antigenotoxic preserving the dna of the cells. https://www.researchgate.net/publication/236911659_In_Vitro_and_In_Vivo_Anti-Tobacco_Mosaic_Virus_Activities_of_Essential_Oils_and_Individual_Compounds

OOOOO. Well then if the mother plant was good then it's not genes. Just a mutation then that's all. It's otherwise healthy though right, or so it looks. But it's nothing gotta do with a def/PH or anything you did. It's not like they pick sides and choose not to affect 1 side right dorm the middle. It's just a mutation is all.

This is a clone I took during flower. I did not notice any weird leaves on the mother.... I shall check the rest of the clones for the same leaves. Thank you all

Genetics bro. If it was a prob. You wouldn't have such weird signs if it was defs it wouldn't just stick to one side of a fan leaf. Looks like an MJ thing going on. 100% gentics.

In my opinion this is not genetic, lets do some check ups based on your diary: 1. Your PH levels are oke. 2. So is your EC. 3. Your temperature is fine. 4. You are growing with cocos, meaning there are not much nutrients in it. 5. It looks like a deficiency, i even spotted some leafs that are sucked the life out of them haha, meaning your plant wants nutrients. Since im guessing your not using autoflowers( they don't need much nutrients) but just normal ones so they can handle more nutrients. I see you are using 1ml of canna coco, you can carefully raise your basic nutrients to like 1.5 or something. 6. You already using cal-mag but that not the problem you are having so don't use more then u already use. 7. You can also try to add some (N)itrogen and a little (P)hosphorus. 8. I saw many tems had stress 9. If you still have doubts, just try to check up your run-off water. If it has like ph 6.0-6.4 with like EC 1.8 you are good. Anything way lower or higher should be dealt with asap :) Goodluck growing :)

That's just genetic, not all phenotypes get 100% perfect leaves 100% of time.
