Ph problems aren't normally a 'spotty yellow' issue...usually it's a lightening of the green, slowly turning leaves to yellow. Yellowish spots with neckrosis (brown) is usually either overwatering (causing root rot) or a calcium defeciency.

Using "Artesian Well Water" I'm guessing it's a calcium thing.

Why are you using bottled water instead of tap, if you don't know your ph's? Can really be a big waste of money, in some cases...Do yourself a favor, and get a test kit or even better, a ph pen.

If you are going to keep using bottled water, I'd get some CalMag Plus, or something similar, asap.

No nutes...?

Ladybugs need a food source to live. They eat aphids, spider mites...
I'd grab a magnifying glass, and look at the underside of the leaves. If something extremely tiny (the ladybugs will look huge in comparison) starts moving around...you've got bugs.
