Fast Buds vs Sweet Seeds

End of week 5 finished! - Keeping up with LST on all of the girls - Turned the lights to 22/2 because of the heat... I wanted to tgive them a break... its gets down to 27C at "night" - I have cut off a few large fan leaves that have been tucked and are now getting yellow - I have some discoloration on lower leaves... looks like a Cal-Mag issue, but I'm not sure. I have heavy Cal in the tap water - Stretching is fierce on these right now and they are drinking 2 liters of water like every 2 days or so - Wedding Cheesecake looks real green and not stretching as much - I started bloom nutes this week because I was seeing preflowering occur on the girls... hopefully it wasn't too soon - Also my BioBizz Acti-Vera has an old label with the old logo. It's looking pretty are and smells strong... still using it but I am weary
