I keep reading conflicting advice on pk13/14 , I've always used it on week 4 at 1ml per litre then week 6 1.5ml per litre what is your feeding schedule for a typical 8 week strain? Do i only need it in week 7 as canna suggests and a few people here,sounds too close to harvest tbh,and while im here how long into flower should use rhizotonic and terra vega? Ive been told to give low N first week
