do you let top layer dry before irrigating/fertilizing again?
got your pH around 6.5-6.8?
make sure environment is right before assuming it's nute-related... can't place what that is.. very unlikely micronutrients in soil, so i'm guessing it's pH or watering habits?
if not, i don't know what that is. if you think yo have been aggressive with nutirents, dial back. try a lower dose after a water-only irrigation with 20% runoff -- next time required.
i see you use pk.. .could be locking things out...
calculate your PPM
P - 50-70ppm is likely okay, but ~50-55 is safer
K - 180-220ppm.. 220 is likely too high. 190-200 is likely good.
Lots of variables impact those generalizations.. so, don't do somethign solely because of what i wrote above. hopefully it fits recent behaviour and what you were thinking to start...
