Update: Charlotte is 5 weeks and 3 days old. 38 days. (from sprout) Last watered today, 1 gallon, with just 2ml of CalMag. I waited 4 days like normal, but soil was really dry and she was droopy, so she must have been really thirsty! So that led me to believe she is drinking more water now. So I think next watering I'll start giving her 1 and 1/2 gallons.
Also, I'm not really sure what to do, I wanted her to fill the scrog at least 50% before I flip, but I'm also afraid of her stretching too much. Wondering if I flower her now, if her stretch will fill the scrog 100%. I saw a few threads of sativa plants during the flower stretch, and wow! The tent I'm in now is only 5 foot. And I have maybe 3 1/2 or 4 feet of that to work with. Only 30 inches above scrog. It is a sativa dominant, with high sativa %, I think 70-30. Any advice on this would be appreciated.
Anyways, also going to be giving them their first dose of FF Tiger Bloom next feeding, getting excited that the fun part is getting close!
