I’m based in the subtropics of the southern hemisphere and bought three strains a couple of months ago - White Widow autoflowering, Girl Scout Cookies Extreme (fem) & RB Gold Leaf (fem).
I germinated them in a sheltered sunny spot during in our winter (August) at sea level & got 37 out of 40. The Gold Leaf & White Widow developed really nicely, but the Girl Scout have been really, really slow and are looking very stunted - maybe 4 inches tall.
They’ve been in small to medium pots with good quality potting mix. I’m about ready to plant them out. I moved them from sea level to my growsite, which is at 800m altitude. The White Widow autoflowering were just starting to flower when I moved them & I thought that maybe I had held them in pots too long but as they were all about 18-24 inches I wasn’t too worried. Since moving them though, all the other plants have started to pre-flower, including some girl scout that are only 4 inches tall. We get roughly 14 hours daylight at the moment. and temperatures are a bit variable - we’ve just had a cool wet spell with almost constant cloud cover / rain for a week or two.
So… Does anybody have a good idea what might be causing the issue (altitude / temperature shock from the move / extended cool wet period / something else entirely) and - more importantly - what I should do from this point to get the best possible harvest?
I was considering pinching out the flowering tips as that usually works wonders with some culinary herbs going to flower - is that a bad idea with marijuana?
Thanks for any help you guys can offer
