Need some help with what's going on, maybe a potassium def or cal mag? I had some pH fluctuations w my soil too. Blue dream and pineapple express auto, 77f 50rh, ffof happy frog perlite mix. Should I give more cal mag and potassium? Advice greatly appreciated.

Looks like a slight calcium and phosphorus deficiency. Looking healthy overall tbh. Unclear of timescale in pictures, i.e. which one is most recent. Make sure you pH is right, 6-6.2 in soil for veg, 6.3-6.5 in flower. Agricultural gypsum will lower your soil pH, dolomite lime will raise the pH of your soil. Test your soil by doing a slurry test. Clean fresh water in a bottle, test pH. Add some of your soil to bottle and shake. Allow to sit for 20 mins and test the pH. This will tell your soil pH range. I hope this helps, good luck
