Listen.Problem in first photo looks definitely like a N abundance.Yes some plants have weird mutations,I had it before too.But in case of N abundance,what I advised was the solution.I'm adding two different photos of my same plant that had the problem.You can't revert old,clawing leaves back to normal but NEW GROWTH is always healthy and normal looking.I flushed with 5 litres of water,no ph adjustment and then cut off Cocos A solution which has higher N in it.Everything looks damn good for me.If this is the case for you as well,you should try it.If new growth is not clawing,then you are safe and well done.But if there is some mutation,it's just genetics,you can keep growing it unless it really,really suffers and everything looks terrible.

Look, week 3 and week 5 photos of the same plant with strict N abundance. (zkittlez from fastbuds)
