I'm one who tops/Fims my autos ....for that extra 2-3 grams, ...the deal with autos (imo) is that any form of transplant shock, seriously delays plant growth and at such a critical time for any vegging auto, many who do potup autos have got to face the reality that any shock, screws yield...one method I have used is once you potup an auto, if it MUST be done, foilar spray with aspirin(Salic Acid) to reduce shock, and avoid over watering ...good luck
