I have 8 plants, all on the foxfarm nutrient schedule. These were planted on 4/20 (ey).
This plant has this only on one branch and I don’t see anything wrong with the branch itself. I am seeing that the other plants are starting to not look AS green as they were. Right now we are using grow big, tiger bloom, and big bloom.
It’s an iron deficiency. Shake your bottle of Big Bloom before feeding. Big Bloom has plenty of iron in it, but it’s not making it to the plant for some reason.
What is your runoff pH? Iron gets locked out pretty quickly with a pH above 6.8.
@MidwestGuy is correct 
Not getting iron for some reason.
It’s definitely iron deficiency, very very rare and unlikely it’s not there. Need to figure out why it’s locked out.
