Growing some spring delights

Very disappointed in the size of my trees. The soil mix I did was not beneficial and feel it has hindered plant growth. I won't be experimenting with the soil again, for Autos anyways 😬. Have been reapplying LST through the week, and have been defoliating trying to get as much light across the trees as possible. Have removed most of the lower growth as I can't see the trees developing a lot of flowers so trying to get the best out of what I have. The Super Kush does seem to be improving and the flowers are engorging :). The other "unknown" is looking rather pathetic, but will stride on and keep giving nutes. Fingers crossed it is a late bloomer. It seems to want to grow into a bush, getting loads of leaves clumped together, and some claw like. I'm guessing the bushiness is genetics. I noticed the leaves have been a bit claw like. Not sure if this is over watering or calcium issue. I don't have brown spots on the leaves and have been supplying Cal-Mag, so probably over watering....? Hmmm, just drenched it... Doh
