Increase stalk growth

A question from a fellow grower:

My new clones are about 4 weeks into veg and I would like to know is there a way to increase the size of the stalk. What can I do to make my stalks and the stem growth increase?? I’ve increased to a very large pot with alot of dirt. I am looking forward to your reply.

Add a silicate and fan to keep plant moving also add a little lst gently bend the plant as if training as the plant heals from the bending it will thicken and stiffen just remember to be gentle you can literally simple crush stalks gently in fingers till they crackle slightly massage stalk in several places repeat at different places every couple days
