Small leaves size.

Yeah I’m gonna say it’s probably root issues in that one like disnoof said

Also remember once leaves are damaged they don't fully recover so it's new growth you need to keep your eye on.

hi there MyKetb , basically you have some sort of root problems from all the fluctuations and issues you had before. So now you need to remove the problem roots. To fix this in a good way try to water with only humic acid twice in a row, then resume your mother plant schedule as before. Do this and normally it will take one week to recover. Hope this helps ! 🚀
