What is wrong with this plant? All others look great.

If all your other plants look fine and you don't have a bug problem. Then there is nothing to worry about right now. Just do the obvious, ph and give a little less food, if you're feeding her

It will be fine, give it a chance........ It can not be "unsafe" to have it near any other plants and there is no need to throw it away just because it has a few funny leaves. It will probably grow out of it and may just be a bit more sensitive towards the new soil you transplanted it into.

Looks like she´s a bit of a mutant. 👽 But I think she´ll grow out of it and do great. Care to open a diary so I can keep up with her? 😄

I can't clearly see on the pic, however, if all the plants are being fed the same and in the same environment, but this one is showing deficiencies, then you should flush it because it might be lock out.

I dont remember what exactly from nutes, but its either overwatering or excess of potash ( i think, not sure which one plays this trick, not nitrogen 4sure) make leaves go so wavy ... She should normalise with time, maybe will be a bit slower to develop ...

So this is royal cheese from RQS. They were transplanted last monday. The plant was looking ok but now after 1 week this happened. I watered only 1 time with 150ml per plant, because I buyed fresh soil, and it was heavy as fuck, so its no overwatering. Should i throw this plant away for safety of other plants?

It may be a genetic error (in this case, don't worry, probably it won't affect flowering) or a virus (like tobacco mosaic virus) or a pest like hemp russet mites. Use a magnifier and check for tiny little evils on stems,leaves and all over the branches, if you see them, is the hemp russet mites. If you don't see nothing, ask to the breeder where the seeds come from :) anyway if this disease affect another plant, it's the virus, if not it's an genetic error :)

Overwatering ??? That light dont help, take her to natural light for photo
