Good that we learnt something here.
With strains like SLH you don't want to defoliate at ALL imo, and in many others opinion in this topic. Maybe some indicas benefit from deflower, MAYBE. I am not sure, I don't do it and my plants look bigger and maybe better than 90% on the interweb. Big leaf = big energy. Why do you think the plant produces leaves at first point?
Big leaves mean huge colas. I've read somewhere that buds actually need leaves for the flowering process and big defoliation can interrupt this metabolism. If you pluck them out they will put more leaves out of buds instead.
Keep that in mind for the future.
And for SLH, it is VERY picky eater.
After stretch, if you had low ec already keep going, but if you are feeding same that you have fed other plants, cut back a bit. SLH can get overfed so easy, and it will stunt the growth for long time. So better keep EC low. Its funny how big buds SLH can do with so few nutrients needed. Great strain but definately not the easiest! Your plants seem nice and healthy, maybe keep on using the same level nutes you have before. They are definately not maxed out yet. I remember when SLH came out, almost all the pictures of it in google were "nitrogen claw" if I am correct with the term? Like this
