Full Moon Plant Indoor Help!

I am using the following setup:

- Blackstar LED - 3 inches from plant canopy. I'm sure that I need to raise the light.
- Organic Soil- with dolomite lime.
- Humboldt Nutrients fed a little less than every other watering(My first FM grow didn't need many nutes).
- Smart pot
- 18/6 light schedule
Symptoms

- First symptom was burnt tips, a sign of nute burn, so I fed less.
- Second symptom: lower yellow leaves.
- Newest symptoms are yellow leaves up top
- and leaf twist

It seems like a nutrient deficiency but the leaf tips are still burnt.

What do? Halp. Here's a photo to help things along.

think you got ph problems bro

What was the NPK values on the element chart on your fertilizers?Also how much did you feed .What was your soil's NPK values (if it was pre-fertilized).Soil's ph should be fine but i'm a little worried on what you fed.
