2 weeks into flowering, my girl has been showing some leaf damage, and on some of the newer shoots, around where the buds are starting to grow, the leaves look like they are burning off and twisted, on some the lower fan leaves are getting spotty.

i flushed them a week and a half ago, and i just added 1/4 tsp mg bloom booster to the water yesterday., i was wondering if some one would know what i might do to correct my prob. by the way, this is my first grow. thank you.
