into 3 weeks flowering leaf issues.. help!!

my Jack Plant is into her 3rd week of flowering
bottom leaves fell as expected
after 2 week top leaves began loosing their color in a strange manner & a few brown spots appeared on them
I thought it might be the proximity to the light so I separated it more.
I was using a NPK 8.0-2.0-6.0 bio-grow organic fertilizer once a week.. but stopped and began watering it down incase of nute burn..
the leaves continue to turn yellow..
AVICE PLEASEE!!

that is not nute burn its more then likely mag deficiency and probly cal too. do u put calmag in the water? check this out
Guide
it basicly goes on to state that it could be you bloom nutes as too much k can lock out cal mag also too low ph can too. read the guide and see if u can find you problem

calmag
u need some of that if it is,i had same problem when i went into bloom,
p.s. check ph that was my problem plus i was putting to little at the time, so make sure u read the feeding chart on the bottles

Agree, Cal/Mag.

You're not putting a wet plant under HID's are you?
