Seedsman Auto Lemon Hydro Grow

So its Week 4 and everything going down hill for this girl. I had an accident in the garden while doing some LST on this girl and it didn't end as well as I'd hoped at all. 1 of her lower branches got caught under a fan leaf, as I gently pulled her branch loose it just snapped clean off, I shed a tear and left her to recover. The shoot that broke off went into a root riot cube just to see what could possibly happen, I know you can't really clone an auto but I've not got much to lose at this point. A few days later and it looked like the wound was healing up quickly, I decided to give her a quick LST adjustment. tucked a few big fan leaves so the different nodes had time to catch up. Everything was going great, till I had a mirror déjà vu. The parallel branch to the 1 that snapped off did exactly the same, barely connected. I ran around the house looking for any kind of tape, electrical tape was all i could find so I bandaged her up as quickly as possible. I'd already lost 1 branch and couldn't stand to lose another so thought it was the best thing to do. As FIMing means "F**k I Missed" have I just FIMd my auto because non of this was meant to happen or is it defoliation and is this going to cause her to Hermi? Before all this happened she was responding to LST really well and put a lot of energy into all of her branches. I didn't realise how brittle auto flowers were and was being as gentle as possible. I've seen hundreds of tutorials on growing and people being quite rough with there plants, maybe the accelerated growth of the auto just made it weaker. I just don't know, any ideas? I'm yet to see if shes been stunted by this ordeal, I hope she hasn't and has a swift recovery. The Root development of this girl has exploded during this week, at the start the were just a few tiny roots which have developed into a whole system to support the plant (she need it) This will be the 4th week I didn't changed the nutrients and I believe there is plenty for the plant to still thrive on, if I notice a deficiency then I will be amending it. I plan to change the reservoir around week 5 as there is still roughly 11 litres remaining. I'm keeping the LED 18 inches from the plant and am still looking to get a PAR/LUX meter so I can properly adjust the height to what they need. As the weather continues to get colder so does my tent but it seem happy sitting at 23'C during the day and 18'C at nighttime. So to sum up this week I've mutilate my auto girl by snapping 2 branches causing unknown future damage, monitored the reservoir and some LST. Can't wait to see what happens next week.......
