You have Tobacco mosaic virus. Curved leaves with yellow stripes or mottling are usually the main symptom of mosaic virus. Unfortunately, when it comes to mosaic virus, there is no cure. An infected weed plant will have TMV forever, though it may not always be actively showing symptoms. If you believe you have a marijuana plant with TMV, your main goal is to prevent it from spreading to other plants!

Hi there! This could look like some sort of moths are eating your leaves and sucking-out your nutrients. You may want to check carefully for bugs/moths/spiders, look everywhere under the leaves, under the pot, into your soil. If there's none, this is probably related to Tobacco Mosaic Virus, as mentioned by our friend @DudeGrowsWeed. If it's the case, there's not much you can do but kill it quickly to prevent the virus from spreading to your other babies (this disease can be transmitted by your hands, by leaves contact, by the soil...it's a real pain in the ***). I'll be around, keep us up-to-date and good luck with your last weeks! 👊

This looks like it could be Tobacco Mosaic Virus (TMV). Here’s a link with info on TMV: https://www.growweedeasy.com/tobacco-mosaic-virus-tmv-cannabis/ I had this with one of my plants a couple of months ago. I have no idea what caused it. But the plant was very small and very slow to flower. I could have kept her growing, but decided to cut her down to make room for a healthier plant. Good luck!
