Fading Too Early?

Could be to much phosphorus as well as over makes leaves pink think looking over the hole plant it's root zone problem.if you can get oxy plus hidrogenproxide give it a good flush throw with it for a week give the roots a good heal hi oxygen and kills any pathogens

Likely a pH problem. Are your plants stems purple or reddish? If not then it's not Phosphorous because Phosphorous deficient plant leaves don't turn purple like that. They crisp up and turn a dead flat green colour. Stems will go from green to stripped red to reddish to purplish red. Leaves that turn purplish when a plant is sick is a micro nutrient issue, namely Molybdenum if i remember correctly. A plant needs literally only like 0.008mg per liter. Very small amount. But if the soil pH is fucked up and out of range then it becomes unavailable to the plant. I see multiple problems with your girl. That's why i say your pH is screwy. Get it tested and confirm before you just start dumping more shit into the soil. Almost every bottled nutrient line is engineered to optimally grow the Cannabis plant. Advanced is the same. A deficient plant due to inferior nutrient products is highly unlikely. If you've been following the bottles feed recommendation then you shouldn't be having any issues unless your pH is out of wack.

Phosphorus deficiency imo. I'd give her some kelp extract or a compost tea.

Can agree, dead parts by colour reminds lack of phosphorus. She needs to bump up pk, in reality all NPK, plus maybe has magnesium issues, so calmag would be smart too. Have fun !

That looks to me like a phosphorus problem as thje purpling of the tip of that leave would tell me that also. I would double check your ph levels and ec that seems like alot of nutrients to be giving a plant. it could be somekind of toxcity builing up over time. Nice looking plant though buddy it does not look too serious I would keep going :) Best of luck for a nice harvest hit up my dm if you need any more help peace out :)
