Sick plants, black leaves curlinng etc, overwater?

[PatSajak]

Are you growing in soil or hydro? Lighting and distance from plants? Regular nutes you use? Room temp? PH of your soil or hydro resevoir?

I'm using fox farms soil, 2x400 watt HPS that i keep between keep around 8-12", (the 2 dieing plants are not directly under the bulb and aren't burning) Room temp I keep between 70-78 degrees, drops to mid to high 60's with lights off. I use Tiger bloom once a week, (just started using it, and started with a light dosage) and I use BigBloom supplement every couple of days or every other day

use spring water 6.4 PH, not sure the PH of my soil, those cheap ph soil meters i got never worked properly for me

I cant' figure out what the problem is, I've got 5 plants I just switched to flowering about 2 weeks ago, 3 are looking great and budding nicely, 1 has been dieing and not budding, and the other one is on that same path, spreading these Black marks all over the leaves, and then they turn yellow and curl up and are cruncy/die and i have to pull them off.. It spreads from the bottom leaves and gets all the way to the top leaves, only the newest growths are green, but the 2nd to newest growths are Rating: 5
