I don't see a whole lot to be worried about myself... Bessy MIGHT be headed for some calicum issues but she looks beautiful as does Jessy! To avoid any calcium issues, I guess I'd tell you to notch down the Top Max some... it's pretty much all nitrogen (NPK: 4-0-0) and a nitrogen toxicity, if it comes to that, would lockout not only calcium but other nutes as well.
Beautiful grow... you've done really well!!
