It appears to be yellowing from the veins of new growth which would indicate an iron deficiency, but what is your soil PH? If its high ( above 6.8 ) the roots won't obsorb it, also what was the PH of the spraying you did?

Sulfur deficiency starts more in between the leaf veins and outward more than from the base of the leaf.

molasses will be your best friend to get some iron back in her...start adding some to your water at about 2tbsp/gallon, and you can mix some in your folar feeding...also if your are lacking P that will cause iron lockout as well...what are you giving it for nutrients? You should be using some sort of "bloom"/"Flowering" formula at this point with an NPK ratio of about 1:3:2...epsom salts just give you K, I'd go grab some dolomite lime which will buffer your soil and give you extra calcium and magnesium...

What kind of soil is this? How often do you water it and how much? How large of a pot is that? How long does it take to dry out?

Trace Elements Sulphur (S) is a component of plant proteins and plays a role in root growth and chlorophyll supply. Distributed relatively evenly with largest amounts in leaves which affects the flavor and odor in many plants. Sulphur, like calcium, moves little within plant tissue and the first signs of a deficiency are pale young leaves. Growth is slow but leaves tend to get brittle and stay narrower than normal.

when you water how much are you putting through them? Yes ffof soil is supposidly strong, but if you have good drainage(which you seem to have), overwatering you wont see droopy leaves, but you will strip out the nutrients from your soil much faster.

the yellowing is normal when doing that, I always do 48 hours complete darkness and my ladies do the exact same thing. That's why i was wondering if you just started blooming them.. They will green back up in a few days. Nothing to worry about
