BRITTLE LEAVES on AUTOFLOWER 67 days from sprout

I don't know WHATS causing this.... started happening about a week ago. Feed is

1ml silica
5ml cal mag
5ml part 2
5ml part 3

Nutrients is big blooms and buds liquid organic nutrients

Both plants are autoflowers. Same age. Same medium. Same feed.

The sour kush is fine...
The bum wine is still growing and fattening up but the leaves look like they're about gone

Ph issues maybe?
