Where s the problem (week 6 of flower )

Burning from being way over fed. Solution is simple...........feed less.

Overfed in probably more than 1 way. Because it is so overfed, it's tough to be certain of any causes... when nute levels are high, it can be 1 nute locking out other nutes as opposed to a deficiency. AN and most marijuanan brands instruct extremely high doses and a bunch of gimmick products that could either be combined with others, and done so by real prefessional agricultural companies or even sometimes a truly useless figment of people's imaggiation. Definitely drop N back significantly. Looks to be locking out K or trace elements, but leaf symptoms are not discrete.
