Aren't you in that MG Garden Soil? Foliar feeding won't compensate for the low ph issue, but it might be a temporary band-aid to a growing problem. (a false sence of security) Sorry, but you'll still pay the price if you don't rectify the potting soil situation and transplant asap.

When asking these questions, it's best to explain WHY you are asking the questions. I happened to just get done re-reading one of your other posts, (plant needs help) and stumbled upon this one. Pretending the Garden Soil issue doesn't exist is folly, as the rootball isn't so easily fooled. It'll still be locking-out moisture and nutrients, which can stress her to the point of nanners and death. And once she stops uptaking moisture, the pot stays too damp for too long, and root rot is not far away.
