The foliar feeding should clear it up pretty quickly. Mag diff. looks strangely like another type of diff....can't recall for sure but check out some plant problem websites and clearly identify your problem.

In my opinion, your plant looks fine to induce flowering, just give it a few days to adjust to its new home. Use some B-1 formula to get it adjusted quickly.

When I had a Mag diff. the foilar spray took care of it pretty quickly. Remember, the spray won't take away the yellow spots you are worried about, but rather feed the plant what it needs to not produce more yellowing (aka continue the diffeciency) Hope this helps.

What type of nutes?
