Nitrogen dif. or yellowing due to flower production?

Hey, all. Been growing two outdoor, in pots, and both have been doing fine. This girl has just started flowering, and i have begun to loose lower fan leaves, due to yellowing. Started @ the very bottom, and has begun to head upwards, staying close to the stem. Have been growing organically with compost tea when they were in veg, feeding molasses-2T per gallon- every fourth day; I will begin to feed FF Big Bloom tomorrow.

I topped dressed today with a bit of compost...wondering if I should give a foliar feed of compost tea along with my other feedings to supply nitrogen?
As for feeding, what are the thoughts on foliar vs. soil feeding?

This is only affecting this plant? The other plant has been treated the same...

Appreciate the feed-back...

I think you could feed'em some tiger bloom!
Big Bloom isn't much for flowering they need more nutes!
No more than 2 tsp TB every other watering?

if they are different strains they may react differently
