brown/yellow spots and leaves folded up

its very weird, but all i did recently was nute the dam thing with alaskan fish fertilizer, days ago i FIMed it, but it has recovered, and started growing since then... the alaskan fish fert says it will not burn, but i think it has.

this happened in 18 hrs. one leaf has some small brown on the jagged edges. some others have brown spots spread evenly over the leaf, but sporatic. and some have yellow/brown spots. the biggest upper growth is slighty yellow, and the individual fingers are folding in half (upwards) the second set from the top is also sagging slightly.

all the problem leaves are on the "top" of the plant.

its not starting from the bottom.

+rep for good help sorry its a long story with no pic....can take pics if nobody has a clue

I use something similar as well
it can burn if you use too much.
How old is it? I always started mine on 1/4 - 1/2 strength.
Here is what I was using.
