Atm mate I’m on using biobizz 0.5 grow, 1lm bloom, 0.5 topmax, in biobizz light mix, I’ll defo get some better photos tonight as they are in darkness atmIf you look at his pic, that plant is just starting to flower. It is far from the end of its life.. This is not a "natural fade"..
Autos have zero recovery time so it is very important to address every issue as early as possible.. To get an idea of what the issue might be we need all of the info on the feeding schedule and dosage. Ppm info is always great, and full plant pics as well.. If it's fading like that on one leaf, im sure it's starting on others as well..
