Hello, first off thanks for taking the time to try to help me, its greatly appreciated. I guess I should start by giving some info on my setup.
I have a 400watt HPS in a DR80 Tent.
The temps are usually 77-81
RH is usually 25-35
The strain is FMS Iced Grapefruit
I am using LC's #2 soil with LC's #1 fertilizer:
6 parts Fox Farm Ocean Forest
2 parts perlite
2 parts earthworm castings
2 tablespoons Dolomite Lime per gallon
1 tablespoon Blood meal per gallon
2 tablespoons Bone meal per gallon
1 tablespoon kelp meal per gallon
The water they are getting is 0 PPM RO/DI water (I have to use Ro/Di because we have chloramine where I live), its usually right around PH6.0 It usually sits for a few days before I use it, so I usually put my air-stone in the water for a few minutes before watering to get a little bit extra oxygen. I have been adding 3-4ml/gallon of Cal-Mag+ every other watering, otherwise its just plain water.
The runoff is coming out at about PH6.5 with 175PPM.
You can check my grow journal if you need any other information:

I first noticed the burn on the 10th and I thought it was due to over-watering causing some sort of lockout. I since let the soil dry till I could stick my finger 3-4 inches deep before feeling moisture, and I just re-watered right as I was taking these following pictures.
First, here is a picture on the 10th, showing just the beginning of the nute burn:
All of the rest of the pictures are taken today, this one is showing two of the plants, the one of the left has one leaf that is so brittle its cracking off:
Here is a closer picture of the plant on the left:
Here is another plant, you can see this one has the leaves curling as well:

Here is a picture of another plant:
Here is a close-up on one of the burns:
Here is the last plant, which seems to be curling the most:
Let me know what you guys think. I also forgot to mention that the plants were all topped a few days ago, will this accentuate burns/curls?
