Blackberry kush auto Dutch passion window grow

Almost the end of preflower and about to hit flower. It’s about 6 inches tall rn I think it’s got at least 5-7 days of stretch b4 buds really start forming. So my guess is about 10 inches tall. I’ve defoliated most of the top leaves and pruned the bottom branches and bud sights. Going to take off the bottom fan leaves and that’s it for any pruning or defoliation. Got some decent natural sunlight this week for a couple days. So growth has been good. Short plant but very stalky so expecting some massive buds. Added compost and worm castings and that’s it as far as top dressings. Will add some type of sugar(molasses or coconut water) a few weeks after the final top dressing and that’s prob it. Normally I would add fish emulsion too but it’s flowering too fast so I don’t want to burn it.
