thanks latewood i think that was my problem ph at 5.4.. i gived it a flushing lastnight with some florakleen.. the roots look white and heathy then i gave her 1\2 nute the ppm was 725 and the ph set at 5.9.. hopefully she'll pull through.. the only thing i really dont understand is when to use the cal-mag or the liq karma.. can u sum that up 4 me? again thanks p.s. during flowering whats the ideal p.h for flowering?
