For staked tomatoes, pruning is different. You leave the top in and knock off the lateral shoots. If it is a true bush tomato (eg Roma) then there is no pruning.

They are a lot harder than cannabis if you are growing indoors because they require buzzing insect pollination. You can aid pollination by touching the top of the flower bracts, gently, for a few seconds with a vibrating device like an electric toothbrush.

Like cannabis they are prone to magnesium deficiency and spidermite attack. Mg def looks similar, yellow leaves with green veins, but in tomatoes the leaves will curl as well. Spidermite attack looks different, tomatoes don't get as obviously speckled as cannabis, instead the leaves take on a bronzed look with speckling noticable on close inspection.

That's it, can't think of anything else atm.
