Looks like a potassium deficiency by burnt straight tips, and further spotting. My other question would be what your ph does from day to day. If it is rising then it wants more blooming nutrition. When you hit the sweet spot it will stay pretty stable. They have a healthy appetite for potassium. Especially in flowering.
You have nutrition burn and calcium deficiency... How to fix it make sure your PPM. EC , PH are good also u can buy add calmag
Veg 600-850ppm
EC 1,2 1,7
Flower 850 1100ppm
EC 1,7 2,2
And your pH 5,5 6,5
