5 Strain Autoflower

Water, water every where and all the boards did shrink. 2 gallons on each 5 gallon fabric pot of 5.9 PH rain water is all they have had for the last 5 days. I think they is lots of food left in the Coco and from what I have been told about Autos they are not heavy feeders. I am a little baffled by the Think Different, why is it not branching out? It looks like one big cola and it has not got any taller. I defoliated the bottom 1/4 of the 4 that are growing just to get some of the bottom leaves out of the wet coco. Also to improved air flow Temps and RH have been with in range 78F-88F RH 40%-70% even with the rain and cold. The Blue dream I'm gonna give another 4 weeks if I don't see any improvement I will pull the plug. gonna give one more flowering feeding in a few days as soon as the pots dry out. that should last them till harvest time and Ill flush 2 weeks out from harvest with Green Buzz Clean Fruits. Hope everyone has a Merry Christmas and have a safe new year.
