hmm - it kinda looks like shes hungry in general.. maybe shes running low on the nutes from the coast of maine mix. I'm pretty sure most commercial soils wont make it all the way thru flower successfully without some supplemental feeding. Thats assuming you arent doing supplemental feeding already. If you have been just relying on the soils nutes this whole time, I cant imagine its lockout - which would point more towards needing a good feed.
