so
your fertilizer is is 12-12-36 npk

that's a boat load of K

no chance your light on K
no chance at all

the ratios in your fertilizer are such that you should be light on nitrogen AND YOUR NOT
your clearly N toxic so you've been over fertilizing badly

water with only plain water until you harvest

next grow
is this a liquid fertilizer?

the appropriate amount would be to mix 2 to 3 mls per gallon if its liquid
or 2 to 3 grams per gallon if its powder

and water with plain water every other

I would consider looking into a fertilizer with a high N content during veg and early bloom maybe something with calcium nitrate

the fertilizer your using is very high in K and low in N

the only reason you don't realize its low in N is because your using way too much
