N or Mag deficiency or other? Leaf tips browning, ...

Hi Cr8grow I think you have Nutrition burn from over feeding and possibly light burn. Will go down with PH to. I like my soil PH to be closer to 6PH. Suggestions- Flushing here now for 1 week. With 6 PH water. This will remove excess nutes. Then only slight feeding till you think she's ready For another flush. Before harvest. Lifting the lights slightly looks a good idea to me 4/5 inch. Hope this helps Good luck

It's a nutrient burn. Do a flush for 1 week and try to rise the humidity too. Good grow 👌

Just a classic nute burn so no big worries 🙌 You're far enough along that you can start your flush a bit early and ride out the end with some Molasses/Water mix until plain water final week (Or however you so choose to finish your plants) Best of luck!

Looks like your plant had a reaction to the bulb change and a over feeding causing a slight root problem. Also looks like they need some more phosphorus. Gl from the White House.

To me it looks like your pH might be off but also maybe it was over fed early on or there is a buildup up of salts in the soil /root system. The best thing to do would be to flush, check the pH and ppm of the run off liquid off you are checking. And add some nitrogen and call mag to your feed schedule.

looks like something is misregulating the pH in your soil.worm castings might be increasing the pH.plant can't absorb elements properly because of pH is out of the limits and this causes nutrient lockout just like yours.you should set the ph in your soil somewhere between 6.2-6.8 , I think 6.4 is a good spot.try to flush for a week with good amounts of water to get rid of the excess salts as much as you can.but if ph continues to fluctuate like this,flushing will not be a permanent solution.it's early flowering,you can get over it
