Hey man everything is looking good. Just gonna throw out some suggestions on what I regretted doing/not doing if you don't mind.
Ok, I regreted not flushing as much, or even a semi flush. Like the make it rain technique, I noticed a little nute burn on your plants (not sure if anyone mentioned it).
Also I would look up a good feeding schedule for flowering if you haven't already, which I didn't until the end. For example what weeks in flowering people add veg nutes, or their bloom boosters stuff like that, like a higher value of K or P.
Also good job on getting that 52 watt, I have some 55 watts myself and I like them.
With watering plants, I just try and make sure they get to have a light feeling in the pot and stick my finger up to the first joint, never let the plant go into night time (especially during flowering) with little to no water cause its basically a wasted night and damages cells blah blah blah you probably already know this haha.
Anyways everything is looking good +rep
