How has the progression of the damage been/how is it when it starts, then gets worse? More details about how you're caring for them?

im on my 2nd grow having lots of problem with ph an yellow dying leaves bout the same ammount of time into flowering as yours ans what i learned on this thread helped me slow it an i think i nearly have it under control, but im pretty sure they be dead by now if it wasnt for this thread, click here = ( https://www.rollitup.org/marijuana-plant-problems/437657-soil-runoff.html)

Yellowing and falling off of leaves late into flowering is normal, though - If everything else with your plants is healthy, I wouldn't be too worried.
