Miracle Grow's got a nute system that hits all at once and destroys the plant at a given amount of time.. i'd say to transplant ur bitches into regular soil.. i bought a bigass bag of plain soil for $1 at walmart.. especially if ur gone for the week, u dunno wat'll happen to them wen u get back! it might be all hell! be safe, man..

If you get liquid nutes, you can add a little bit to your water system.. its somethin to invest in.. I bought 3-4 bottles.. for each stage, even.. I'll be doing it to my darlings when they're ready.. yours are ready..
