You have a ph in your substrate is off. You are in lock out on several nutritional needs. Run enough of correct ph water through soil till run off reads in range then replenish nutrition.

Deficiency?? Excess? Neither?
Grown this strain before and had the same issue.. not sure if its a CalMag deficiency entirely. pH has remained at 6.0-6.5 or so in soil and didnt show signs until recently, seemed to have worsened after just two days of only CalMag and Ro water so I bumped up the bloom nutes.

Plants deteriorating rapidly, pls help
Plants not looking good! Help! White tips at the end. Brown patches. Leaves curling. I've been feeding it 0.5L Advanced Nutrients Coco Big Buds. The light was fairly close, at 30cm. I've raised the lights to 60cm. It was also very humid, so I've opened the air vents .

What kind of deficiency? What should I do? By the way, they're autos.
What kind of deficiency do I have going on here? I gave a good dose of calmag last night. The first signs were the dark spots on the leaves. Been feeding ff bloom nutes every other day, 1/4 to 1/2 strength. started from the bottom. Leaves turn yellow and then dry up.

Deficiency
Could you spot the deficiency? Calmag? Light burn from droplets of water? 6weeksThis auto Critical FastBuds has been growing slow and now is showing stagnation signs, and her sister is now flowering and looks much better, but lower leaves looks the same on both.

Late Stage Nutrient Issues?
As the plants near the end (last two weeks) should I expect to lose virtually all the larger/medium fan leaves as the plants drain them of nutrients or is that a sign of overall nutrient deficiency?
