Im a couple weeks into main-lining in dwc. My ppm with GH trio and well water is pretty low and stays rather stable around 550. The leaf tips have been curling under for a couple weeks and I thought it could be due to low night temps in my basement. However now the tips of some of the new growth is beginning to turn yellow and move down the leaf between the veins. Whats going on here? Too much food or too little. I used cal-mag at first but once she looked better i stopped (i think this might have been my mistake).IMG_2643.jpgIMG_2639.jpg IMG_2644.jpg

That there is the claw. It's usually associated with nute burn. I have not had a single kush plant grow without clawing on me and it has never affected yield quality or flavor of the bud.

I agree with popcorn that looks like a case of nute burn. Give her normal water without nutes for a day or two and see if she clears up.

Thanks for the help guys. So in your opinion even though I'm feeding at a fraction of almost every recommended level i can find (Most people say way over 500ppm for a plant in full veg) this particular lady can't take it. I would just hate to stop all the food to find out it was a deficiency of some sort after all.
