Not really sure about the direct cause, but a few things jump out at me...

No intake for fresh air? This is a must.

Fox Farm has recently opened a new production facility in South Caroline and people have been reporting problems with it. Are you East of the Rocky Mountains by chance? How did the soil look and smell? Was it light and airy? Did it smell fresh? Always good to add a little extra perlite for better drainage and air to roots.

Container size might be a little too small for a plant from seed. Right about now the roots are trying to stretch.

Keep in mind that if the feeding water or run-off have any color or tint it can skew the results of color-coded ph tests. With that said, how long since your last transplant?

Foliar feeding shouldn't be necessary unless it's to correct a deficiency. I would hold off on that for now until we figure out what's really going on.

I think a transplant into a larger (5gal) container wouldn't hurt at this point (transplanting in flowering is not a big deal, as long as you don't damage the roots). Get some fresh soil with added perlite (about 25-30%).

Personally I'd also lay off the additives and stick with the A+B until she gets healthy again.
