i was thinking that it was an immobile nutrient at first, that is why i suggested what i did...but when was the last time you fed them N? alot of people cut that out at like the 1st. week of flowering...the deficiency is showing up top mostly, and a few in the middle...but it is starting on the fan leaves...everything is stored there...and used up first there as well...if its been a while since you fed some N that could also be a problem. but to narrow it down...heres what i think could be the problem...cal/mag, iron, or N.
He is using a 10-30-20 Bloom Booster, once at half strength, once at full strength, consecutively.

Ok so I condensed my journal on this plant. Here's the major events in it's life:
8/10 Purchased blue cheese clones and repotted in 1 gallon container using Miracle Grow
8/11 Clones infested with mites, started neem treatment
8/15 No more sign of mites, continued spray every 3 days for 2 weeks
8/31 Replanted in 3 gal container using Miracle Grow (I thought I fed with veg nutes a couple times before that, but I dont see that in the journal
I must have been thinking of the clone I kept for a mother)
9/4 Switched to 12/12
9/9 Did initial LSTing after first watering since going to flower (actually first watering since repotting on 8/31)
9/18 Next watering. Started with half strength bloom nutes. Made final adjustments to LST. I got a bit rough with this adjustment since I had to pull around some branches through tight spaces.
9/26 Latest watering. Watered with full strength bloom nutes.
