What is this and how to fix this issue ?🙏 What is this white on leaves and you can see leaves deformation they are not growning the same in two side.??
You seem to be suffering from copper deficiency that is quite rare that means either you using non tap water or you actually have a pH fluctuation problem or a root problem and is showing as copper deficiency. The fact that the leaves are all dark green and you are in early flowering is typical of copper deficiency.
I hope this tip helps you out good luck with your garden
Looks like it could be a mutation. That's a guess but if you Google Cannabis Mutations in the images search side. You will see pics of plants that have plants that have a similar look. And if it's Genetics not much you can do FROM WHAT I UNDERSTAND. maybe someone else will know of a way to switch a mutation around in all ready growing Cannabis plant but I do not.
Hello.. Hope you are well.. Leaf curl to the sides is usually a indicator of ph shifts.. Keep an eye on ur run off n adjust accordingly on nxt water /feeding.. Stay safe n gud luck.. 👍🍀
