Help me Rhonda!

1st grow, nothing special one plant from bagseed. Anyway, everything has been pretty by the book so far... and my baby has been doing great. Then the weather changed, its been cold (but not frosty) raining, and gloomy for a little over a week now. The leaves are starting to turn yellow (which I think is from the lack of sun) What should I do.. she's been flowering for at least a month if not more, and I am afraid the rain and lack of sun is gonna ruin months of care that I put into this jammy. Any advice. Also Four more days of gloom and rain in the forecast....See pics...Stupid East Coast Weather.

Actually looks like a nitrogen deficiency to me. Plants get plenty of PAR lighting even when it is cloudy. Looks like you have at least 3 more weeks to go, so plenty of time to continue feeding before a flush.
