Hey mate! From the photos I can see that the point leaves are with a little burn, so you give them a little much nutrients, I would suggest to give a flush, maybe 3 feed with only water and after that give again nutrients but with a low dose, and increase gradually!
I think you need to give a little more water to the plants too, and don’t let the soil dry completely, because the benefic microbes die and it’s not beneficial overall do let the soil dry completely!
Wish it helps mate
