dutch bucket recirculating grow

This is my first autoflower and my first led grow. Running a recirculating system that has always worked well with photoperiods for me. Appreciate any feedback on autos. My fastbuds strains have popped up nicely and off to a great start so far. My setup is 5 gallon buckets lined with 120 micron paint strainer bags. Medium is perilite. Drain is 1/2" pvc pipe set 2 1/2" from the bottom of the bucket. The buckets hold about 1 1/2 gallons of water in the bottom so there is not an issue of drying out if there is ever a water pump or flow issue. They are draining into a 2" pvc that returns to 15 gallon reservoir that is aeriated 24 hours with an aquarium air pump. An aquarium powerhead pump delivers nutrient solution to the plants through 1/8" irrigation tubes. Currently running 30 minute cycles of water flow every 6 hours. The plants seem to droop a little with more than that. I plan to slowly increase the pump time until i get to 24/7 recirculation. Lighting with a galaxyhydro 1000w full spectrum led. This is my first experience with led. 24" seems to be a good distance at the moment since the plants are towards the edge of the core coverage area. I have also added a 23w cfl 4" from each plant to stop them from trying to stretch. Feeding RO water with GH maxi grow line of nutrients. Only going to feed maxigro, maxibloom, and calimagic unless I see any issues. UPDATE DAY 7. Gorilla glue 2 is not developing very well. I thought it was suffocating in the rockwool, so I cut away enough to expose the taproot on day 5. The roots are slowly making progress.
