depends on your budget, i went with advanced nutrients but its spendy. another thing is to go with something you can get at your local shop. it sucks to run outta something and have to wait for it to get shipped to you. My local shop is gonna stop sellin advanced cause the owner had some ordering issues with them and now he has pissed off alota people that use AN around here.
But deff go with something that has a easy schedule to fallow. AN has a online nutrient calulator you can adjust the weeks and rez size
It's my 1st grow. I use GH Flora 3-part, my bubblegum clones are 18 days into flower, big as a MF..foolproof nutes..plants had NO problems, my fan leaves are deep green, as big as your hand..GH all the waay!!!!
