Lockout or not enough nuts

I have had this exact same thing happen to me before and it's a soil ph issue . The plant will lock out taking calcium and magnesium and other nures . It looks like a Def but it's a lock out causing the Def. It happens to my plants when my soil ph drops below 5.9 . Make sure your ph pen is calibrated with some ph 7.0 solution. And I would wait till it dries out . Then flush with a 7.0 solution. And feed it your normal feeding at 7.0. Try to get the ph up above 6.0 snd thr plant will start to up take the cal and mag again hit me up if you need to ask any other questions
