First Grow - Trying to F1 Autos

WOW - they stretched a lot!!! I thought they were going to stay super small Figured out how I messed up earlier -- I was ph balancing the water BEFORE nutrients. Got it fixed this week (to PH after adding nutrients) Day 36 July 2 fed water 600ml 6.5ph Day 36 July 2 just before night time the plants tops looked a little saggy.. adjusted the lights a bit higher Day 37 July 3 fes water 200ml 6.5ph... plants still look a little saggy at the top Day 38 July 4 am fed each plant 1L of bloom and calmag pH 6.6 and setup camera. Minor leaf tucking Day 39 July 5 am water pH 6.5 about 300ml each raised the light quite a bit (noticed pretty bad light burn Day 40 July 6 fed each 400ml of water 6.5ph Day 41 July 7 pH 6.33 540ppm bloom ao 1150ml each plant Day 42 July 8 ph6.38 400ml water
