Hey so this is my first time ive gotten this far and I need to know when to start nutes I don't want to burn them . The first 2 are 5 weeks old . Cherry Rush . 60/40 coco coir/perilite . The last is Cannaloupe , it's actually 3 weeks old same mix . 2 60 watt cfls on 18/6 cycle . I have the fox farm trio I plan on using . So far all I've been giving them is a water/cal mag mixture every other day or so when they are dry . Please help me out here ! Thanks !
