Yellowing Leaves, nute burn???

[Vunit]

Ok some leaves, mainly in the middle of the plant is yellowing slowly. At first i thought it was N deficiency, but today, some of the leaves are starting to show browning on the leaves.
Could this be nute burn?

Specs:
8 cfls at 2-3in away
8 weeks old, 3 weeks into flowering
Fox farm ocean forst
Water - distilled water
Nutes - bloom plus 10-54-10
bit of epsom salt (just the last watering)

the last watering consisted of the bloom plus and pinch of epsom salt.

Do you know run-off pH? The brown leads me to believe fert burn. How much bloom did u give it?

bout half of 1/4 teaspoon for half gallon, so its what the directions says on the bottle.

Your soil also has nutes in it on top of that. Can you take a pic looking from the top of the plant down? I would like to see the whole thing.
