-Let the soil dry out. I wait for the top surface to completely dry, then wait for the plant to slightly droop, to know when to water.
Then you can just give a slight tilt or lift of the pot when dry, and after watering, to get a feel for when to water.

Still kinda early in flower; Id go = feed > Water > Water > Feed for now since your plants still look dark green.
-If they start to show a lighter green, then go to a f>w>f sched.

Trimming should be done in veg, all the way up to the first 2-3weeks of flower. After that, you dont wanna stress em.
-Dont trim any leaves
