Yellow fan leaves
New issue starting week 5 of bloom. The lowest big fan-leaves are getting yellow and that very quickly. She got a organic Biotabs PK Booster compost tea 3 days ago. It looks to me she wants more Nitrogen. Should I add molasses? If so how much? Or is it another issue. PH is ok.

Deficiency help
What deficiencies are these? I’ve flushed her, ph’ed her water and I’m giving her a good amount of nutrients - no nitrogen for the past two weeks I think. Is this just an age thing? I don’t need her to look perfect before harvest, but I’m afraid it’s affecting the bud maturity.
