I have a blueberry auto flower that has gone droopy on me. She is about 3 weeks in flower. Being that I work at home and they are a couple rooms away, they are always kept in the ranges they should. 5.8 ph, temp 76-78, water temp never over 70, and humidity 40%-50%. Currently feed them the GH trio, right now little Beastie Bloom with some MPG 0-0-2 in place of hydrogro all is about 1200 - 1400 EC. The roots are crystal white, some of the best I have grown. The light is a 600 watt 20 inches from plant. And is on 20/4. I know I have good exchange the sides of the tent are sucked in.
Yesterday I did an EC check on it because it had been drooping and it was about 480 EC. I did change the bucket to straight water and MPG and the perked up after the lights came back on but was dropping again today. Did a bucket change today right before lights out with a full comp of nutes. I did add an additional airline because the roots are so tight in the bucket, probably due to I like to drop the water level a little in flower. About 3 gallons.
I can usually figure this out, know these blueberry autos pretty good, been getting up to 10 oz off a plant. So they like me, and I like them. lol Any help would be great
