good sounds like you have it dialed in to be honest i have found strength needed is normally reflected on brand i used canna aqua at 1.2 but growth tech 2 part at 1.8 on the same clones go figure
50 oz with autos sounds unreal
50 oz with regular strains mate, i use canna aqua and its strong stuff i find a little goes a long way, ive tried vitalink max and that is a real light nutrient you can easily go up to 1.8ec in flower with that stuff, strecth is also caused by day and night time temp drops if you have more than a 15 degree drop in temps at lights out this will cause plants to stretch it can also be in the genetics, having a fully dialled in enviroment helps loads, the size of this auto and my previous grows has now forced me to take the scrogging route for the future
just for the record ive never had an auto over 1.2 ec using canna aqua
