I stopped useing pro mix for this very reason.I dontthink it has enough dolomite lime to stabalize the ph in the end of flowering cycle.Mine allways looked healthy until the last few weeks of flower.I added a teaspoon of lime to a gallon of water and it fixed most of the problems on my last grow with that soil.could you have overfed?..peace

What did you replace the promix with? I was thinking of going with Sunshine #4.
We feed/water this room with 140gallon res.. Would you put 700ml of lime in the res with waters to help fix the PH of the soil? I really need to check the PH of the soil.
i get weird leaf twisting like that in my aero if my ph is off for more than 48 hours. so my first thing to say would be check that ph.
also i'd pull those dead leaves. that alone will help with the mites as much as whatever your treating with.
Still no luck with this one.. Ph is right on :s Thinking about flushing.. but really that would be about 1400 gallons of water for a double volume flush (15 gal pots x 49)
I wouldn't flush quite like that. For one thing, that's an insane volume of water like you're saying, for another you're still trying to get them finished, right? Clearex or similar, do a watering with that, see if they respond, if so try another watering and then feed at half strength, see what happens.
