^^^^ this .
I was quietly lurking and was gonna give my 2 cents , first …. Those lower ugly leaves are old fans as stated. Once they become damaged , they will not recover - so I say clip them off.
Also , zero reason to check runoff. If you are “ controlling a reasonable amount of feed “ , runoff numbers are moot. If you feel , they are stunted - that is because of your feeding. They look pretty good. Remove the ugly shit and carry on. Top dress takes time to breakdown so if you keep loading more and more without it being exhausted , then that where your high numbers come from. Autos just need simple things , not constant high feeds or baking soda or whatever broscience is out there. It’s just a stupid plant.
It literally would run off the medium alone upfront ( without feed ) for a few weeks THEN it might need a feed bump becahse it exhausted some of the medium. It’s really that simple.
If you start adding baking soda or some other crazy shit like that - you are sure to screw up this plant.
Just water the thing temporarily- No nutes - nothing.
‘Let the plant try to work thru excess. If it doesn’t then , problem was from your hand.
