Is it: A) Nutrient Burn B) Nutrient Deficiency C) Heat/Light Stress D) Normal fade to the finish line Auto growing in FFOF soil, approximately 9 weeks old, feeding Jacks 3/2/1, Full details in “One Plant Greener Than Others” thread. Last 2 waterings were just tap water, Cal Mag and “Photosynthesis Plus” , pH adjusted to 6.8 and watered to about 5% runoff. First runoff was 6.4 pH 1,400 PPM. 2nd was 6.7 pH and 1,100 PPM. Plant is bulking up pretty rapidly now and seems extremely healthy aside from the handful of shitty looking leaves around the inner of the plant… ![IMG_9018](https://global.discourse-cdn.com/growingmarijuana/original/4X/4/3/c/43cad5769d992d703c3d7e2e5a2365585443ae03.jpeg) ![IMG_9017](https://global.discourse-cdn.com/growingmarijuana/original/4X/e/b/a/eba65a1d47cbd735fa46b6331f3b6fadecd1a3b5.jpeg) ![IMG_9016](https://global.discourse-cdn.com/growingmarijuana/original/4X/a/9/a/a9a2ce76de7a7d5e3a96a9922482842facc47b20.jpeg) ---

Completely normal. Keep your ppm around 1100 and your ph around 6.5 to 6.9 and youll be golden. Shes growing nicely. ---

Welcome to the Community , Nice large cola. I see the leaf’s curling up a little on top Of the plant and also to at the bottom. Some discoloration in the leafs. 1400 PPM could be a little high for auto plant in flowering stage. Good luck! ---

Pics don’t really do that top cola justice, it’s really developing beautifully. As are the “tops” of the other branches. It’s really a beautifully structured plant to me, with very long bud sections on every branch. ---

Quiet around here these days! I was expecting to get a lot more feedback over the past week. Most recent runoff from straight 6.8 pH adjusted tap water was 6.8 pH and 1,100 PPM so nutes are dropping, albeit very slowly, and pH looks good, so I’m assuming this maybe a combination of some previous A and mostly D, a normal yellowing as she approaches the finish line… ![IMG_9036](https://global.discourse-cdn.com/growingmarijuana/original/4X/0/7/a/07adce775d081392cb1470a105026c0860baa510.jpeg) ![IMG_9037](https://global.discourse-cdn.com/growingmarijuana/original/4X/2/4/9/2491d35d19d1ff9802dc44b9fcb95a20801c3a4a.jpeg) ![IMG_9038](https://global.discourse-cdn.com/growingmarijuana/original/4X/a/c/1/ac1a57811047640a4c0d70d916bab118b138f843.jpeg) ---

I agree with you. The autos that i have grown weren’t too happy over 1100 ppm. Last pics look like A mixed with D to me. ---

She drank less water over the last couple days so she’s definitely nearing the end. Runoff PPM was down to 850 so she’s still taking in nutrients, pH was perfect at 6.8, down to the last few fan leaves now but she’s still looking good so I think everything is looking ok for the home stretch.
