1st picture: Looks like molybdenum deficiency, happens only when pH isn't in the good range, and CalMag deficiency also then can be also caused by bad pH, due the differences of nutriments absorption at different pH level.
2nd : Totally agreed with
@Imagine, for me its phosphorus deficiency.
So all can be fixed or upgraded at least with right pH control and enough feed. As flo has begun be careful root stress in these times might be deadfull.
Hope you will cure them and see them BLOW 😍
Again good luck mate !
