Hmmm, the new growth on all of them you say...

Could you possibly get a photo or 2 up ? Maybe use your telephone camera, but be sure geotagging is off if it is a smart phone. You could give yourself away, guy in my city got busted because of this !

Without photos it is really hard to say... Some plants act freaky from time to time, but all 7 plants growing strangely ? Hmmm....

Interesting...
