Clawing + Burnt Tips + Stunned Growth = Nitrogen Toxicity 👌

Your problem is nitrogen TOXICITY..... WAY too much nitrogen ... flush it out with 9 gallons of PH'd water (3x the size of the pot balanced to between 6.0-6.5PH) and then don't feed until it completely dries out... and when you do, choose a nutrient that is not heavy on the nitrogen to compensate for having so much in your soil... I'd go with just bloom nutes which give a little bit of nitrogen but more Phosphorus (P) and Potassium (K)... You don't have a diary so any answer is going to be a bit of a stab in the dark... Do yourself and the community a favor and start one... that way, if you have other questions or run into other problems down the line, we'll have a lot more information on which to base our advice! Good luck!

That size plant I would start to feed in a week only, maybe that's the cause ??? Have a look at that https://www.growbarato.net/blog/en/deficiencies-due-to-excess-nutrients/ Less is more in weed cultivation Good luck !
