hello. im using a drip hydro system with 1000 watt lights. feeding advanced nut. im 2 weeks away from harvest. but 80 percent of my leaves are turning yellow from the edges, or completely dry up. i tried taking it easy on the nutes, i tried raising my lights non of it helped. will this problem affect the quality or quantity of my crop and how can i prevent this on my next grow. happy holidays

yellowing toward the end of flower is pretty natural. the plant is using up all the stored energy in the leaves.

Hard to tell without pics but if they are healthy and yellow could still be a nitrogen deficiency evn that late. If they are burnt and yellow could just be burn. In that case there's nothing to do. 2 weeks left just keep using plain water to do a flush finish. If you don't feel heat off the lamp from your canopy it's probably not heat. You would be doing yourself a disservice by reducing your lights in the home stretch.

if they are burning from the tips and yellowing from the tips its a nute deficiency. go here. need a picture, but this might help. http://www.greenmanspage.com/guides/plant_abuse.html

If it is just nitrogen deficiency just keep doing what your doing. What nutes from advanced are you using exactly? just curious.

well right now if your using all those. you would prolly have too much potassium, giving yourself a nitrogen deficiency. I would just take overdrive out all together and maybe go just a tad easier on connisuer b.
rhino skin, sensizym,bud factor won't do anything.

Not sure that 80% yellow with 2 weeks to go is healthy. The more green healthy leaves you have right till finish the more the final weight and less weight for yellow leaves. Could be drifting ph in the soil ,salts build up or crap nutes with little N.
