Afgan Kush Auto

Hi all, The girls have had an odd week. They were looking healthy and green to start with but as it went on there was a real lack of growth and they were gowing very pale. *The Afghan started acting a bit oddly. Her leaves clawed, curling right in and twisting. My light, temps and humidity were all within the correct parameters, give or take, so it had to be feed...* I'd only prepped the coco coir with CalMag and Root Juice and that's what I've been feeding with but a couple of days ago I added 1ml of biobizz grow to the mix, earlier than I normally would, and they've boomed. *The leaves have opened up as much as they can and there's been good growth just within a few hours of feeding.* It's the balance of how to feed autos against how to use coco coir that I have to get used to. I think it may have put them back a few days but I can only wait and see. On a side note, I'm really happy with the mix of coco and Perlite I'm using. Very soft and airy and drains really well. Thanks for reading, see you next week
