Durban Poison [Males] Outdoor Kratky

I'm a little disappointed with the slow growth. The location of the plants outdoors gets a lot of shade this time of the year, only about 6 hrs of direct sunlight per day. I would consider moving them, but they are here for stealth reasons, not visible to any neighbors. Since I'm growing regular seeds I also don't want to use my grow light, I've read that red color light will increase the chances of males, while less light and in the blue spectrum will increase chance of females. Temperatures have dropped quickly this last week, but forecast shows higher temps again this week. I've been increasing nutrient concentration gradually, some leaves are showing small brown marks, I think that could be bugs or a lack of nutrient if anything. Looks within normal growth though. I have a neem oil + soap mix that I used as a foliar spray this week as well, if there are bugs causing leaf damage I don't want that to continue or worsen. I'm convinced at this point that this is the wrong time to grow Durban Poison, too late in the season. I was just too excited after getting my seeds, I planted a few right away. In the future I think I could do really well with autoflowers in the late season like this. I am really excited to grow the rest of my Durban Poison seeds in the next growing season. And I might be speculating too early in the grow, we'll see how these turn out in a few months. Hopefully they'll be better than I'm giving them credit for right now. 😅
