Blackberries & Elephant

I'm a little bit unhappy with the appearance of the Auto BBK. I've raised the seedlings in eggshells filled with some light mix, and probably hurt the roots when transplanting. Although I've done that successfully with autoflowers before, that can be a bit risky. Autoflowers tend to be sensitive towards any stress early on, and especially when it comes to their roots. And if they get too stressed they basically stop their vegetative growth and start flowering. I hope that's not the case here. On the other end, I'm quite satisfied with how the Elephant is doing. I've fimmed it, and it's the first time that I've applied any of such growing techniques to an autoflower. Why did I do that? * It has done well so far and doesn't looked stressed or anything. * It has a slightly longer life cycle for an autoflower of about 13 weeks. * According to the breeder's description it can grow quite tall under optimal conditions (i.e. up to 2m). However my tent is only 1.6m tall, and with the in-line fan mounted inside, the plants can only grow a bit taller than a meter before hitting the light. * Both parent strains react well to topping etc. according to the breeder's description. Let's see how that turns out, and let me know in the comments if you have any questions, experiences, or opinions in that regard!
