N Deficiency could be one of the culprits.....But im leaning more toward a K deficiency. Note that potassium starved plants initially appear healthy. And deficient plants are susceptible to disease. Symptoms include the following: older leaves (first tips and margins, followed by whole leaves) develop spots, turn dark yellow, and die. Stems often become weak and sometimes brittle. Potassium is usually present in the soil, but it is locked in by high salinity. First, leach the toxic salt out of the soil and then apply a complete N-P-K fertilizer. Potassium deficiency causes the internal temperature of the foliage to climb and the protein cells to burn or degrade. Evaporation is normally highest on leaf edges, and that's where the burning takes place.

The progression of the deficiency symptoms at a glance: Plants appear healthy with dark green foliage. The leaves lose their luster. Branching may increase, but the branches are weak and scrawny. Leaf margins turn grey and progress to a rusty brown color, and then curl up and dry. Yellowing of the older leaves is accompanied by rust-colored blotches.
 
Well if its in its last 4 then I would just give it a nice flush. And continue your feeding schedule until the last 2 weeks then flush her again. Flush with unsulphered blackstrap molasses. It gives her some extra carbs for aroma and essential oil production. But note that a serious potential problem with seaweed is its salt content. While it is unlikely that you will add sufficient seaweed to seriously upset the balances of salt in your soil, it can happen. So that might be a nute lock out problem from to high of a ppm in your soil. So when in doubt flush er out! []Deace!
 
Well foliar or not the plant still absorbs dissolved salts. So it is absorbed by the leaves and distributed throughout the plant and eventually goes to the roots which in turn raise the ppm of the soil. []Deace!
 
those organic nute are supposed to last 2 months i had just gave it bat guano and feed it seaweed regularly
i stopped since this stated happening but i checked the ph and all seem to be fine
 
thank god it was just the fan leaves but i have to take care i still have a month to go ... i usually water towards sunset but i had moved it and changed the watering schedule to afternoon maybe it was some sort of root shock when i watered in the afternoon it happened so fast like in 3 days
