Hello my friend, raise the pH to 6.5 for this phase of the grow till harvest. Plant looks great and recovered well from the last issues. But your pH is too low for this phase, the seedling and frowing phase can keep it around 6 on soil. Early flowering you want 6.2 and mid and late flowering 6.5
These are the best pH values for the plant to uptake the necessary nutrients.
Merry Christmas buddy! 💚
