leaf problem

Before swotching to flower i had a ph problem beacause the ph pen was decalibrated so soil was too acidic. After i fixed it and the plant started groing again then i switced to flower . About two weeks after in flower stage bottom fan leaves started yellowing like in the picture and i thi k as the time past its going upwards to the other leaves . Ihave to say that when i had the problem i thought it was nitrogen burn so i stoped adding nutrients just ph water to fix it. Afteri fixed it i added microdoses of nitrogen and more phosforus cause of flowering. Isthis normall or its again a problem . In the photo i have like the stages of the leaf that are yelloing so i can help you more tell me.

Hey Giannhs without knowing age or a full pic of the plant it is only guessing but this looks like normal leaf aging as flowering progresses to me.
 
OK that helps a lot so I can say with confidence that you don't have a health issue other than they look hungry for nutes to me so you may want to increase some. It is aging out early so using lower leaf stored nutrients to feed the flowers. Don't go overboard as the die is cast and those leaves will not recover but new growth will improve in color. This probably started with your pH issue causing some lockout and then continued with under feeding nutes. It should finish with this although maybe not as good a yield as might have been. We live and learn every grow if we do it right! Good luck and happy pharming!
 
looks like a nitrogen deficiency. Even when PH levels are off people tend to think that adding fewer nutrients is the resolution when in fact it's not. when the plant color is pale green and the lower leaves are yellowing and dying off it's usually a nitrogen deficiency.

Correct the PH (6.5 is optimal for soil), make sure you have good watering practices and add nutrients per the recommendations on the bottle (s).
