look like bigger plant is suffering from magnesium deficiency, and smaller plant is probably rootbound and suffering from nitrogen deficiency. https://loudclouds.co/wp-content/uploads/2016/07/marijuana-deficiency-chart-jorge-cervantes.jpg

Sick leaves, good buds Some leaves look sick. (Last photos at 8 weeks) Is this an overdose? Do I need to fix this? From fertilizers, I apply only ripen. I plan to give it 2-3 times and then flush and harvest. I know that ripen helps to end life and makes the leaves turn yellow, but not so!
