Hey. Well some easy Grow,Bloom, micro would do you good. And make it easy for yourself.
Biobizz and so on is good to keep it organic. Or if you want to keep it fully organic worm castings as a top dressing might do you good. You will need to get a cal/mag also. You have many options here. Biobizz calmag is good. Or cal powder from Green House Feeding + Epsom Salts will make a great choice for a calmag + sulphur.
As for defol.. you shouldn't do any defol until you are out of the pre flower stage. Bud sites don't need light until they are in the fattening/ripening stage. As your plant is still in a process of growth in pre flower, (so its the leafs that being energy to to your bud sites, (not light direct on them). So steer clear of defol until you are out of pre flower that's generally 2-3 weeks once you see stigma (pistils, white hairs that come from your grow)
If you need any more advice, feel free to DM during your grow.
Good luck
