First Ever Grow - Orange Sherbet Auto 420FastBuds

Day 22 Is it already flowering ? ? ? Is this stage pre-flowering or what the heck? Day 23 I do some light defoliation on the bottom part, only to help ventilation, otherwise all leaves look quite healthy and strong. Very rough to the touch. Like sandpaper. Day 24 Some tidying up using garden wire (the one that's covered with that soft green plastic coating) Day 25 I believe they are stretching Day 26 And they stretch some more Day 27 Some more light defoliation here and there to increase light penetration in certain areas. Maybe I am overdoing it. Day 28 Wish I had installed a net so I could keep everything at the same height. Feels like I;m about to get in trouble...
