if u cant get ur hands on a ph down (diluted muriatic acid or phosphoric acid) get distilled vinegar, it cleaner. u know what im probably wrong about it being a nut burn, if the tips are not dying and getting all crusty fast then its just a dificiency (the pic isnt clear) and the yellowing says dificiency. the best way to see if ur feeding to moch or to little is by knowing ur ec (electro conductivity). get a tds meter (fairly cheap) a beter meter would be a tds/ec meter (Truncheon Meters are the best about $115) . check this post

its probably a mg and n dificiency (most common) treat with npk and epsion sait 1-2 tps per gal epsion sait must be desolved or u can get some cal-mag
good luck
