Long overdue pictures also help, please

So I need some guidance in terms of where or how to proceed next. I feel I am not getting the growth I should out of my coral and it's really frustrating. I am thinking my placement may be wrong hence the terrible attempts at coral shots on an iPhone. A little info:

-Tank: 89 gallon with 110 pounds live rock in tank and sump, has been running 4 and a half months.
-Lighting: 4 kz superblue, 1 kz fiji purple, 5 kz coral light
-Circulation: 2 mp10 wes plus 1400 gph eheim plus 700pgh hydor k.
-Sump: huge with cheato plus red macro
-Skimmer: Vertex in-80 ( small I know but does a great job)
-Other filtration: 2 little fishes reactor with carbon and gfo replaced every month or as needed
-Additives: Calc (11 ml/daily) and alk (22 ml/daily) dosed via brs dosers, coral snow with zooplankton fed 3 times a week and red sea a/b 3 times a week.
-JBJ Ato from a 20 gallon tank.
-Fish: 2 false perc's, 1 tiny regal tank, 2 yellow watchman's, 1 banded goby, 1 barnacle goby
Inverts: one sand star, 2 cleaners, 25-35 hermits, 5-15 astrea(?) snails, 10-15 nassarius snails.

I'm a student so time is limited as well as space so I have had to be innovative
I currently use tap water. I know, I know. But I don't have a tap I can hook it up to and refilling the top off with spring water is a little much. I change 5-10% bi-weekly. I do not use kalk in top off water but probably should although my coral needs are very small.
Currently I am sitting at.
Alk: 6-7 dkh
Ca:540
Mg: 1300

Solid growth from this one.

Tri colour I have yet to see any growth in about 3 weeks since i've had it

Frag of i don't remember from Coral master, no growth in 3 weeks but feeding tentacles out at night

Mp10's doing an awesome job

The bench I built to house more aquarium stuff. Only way wife allowed it.

The dosing/ATO/Controller and wiring in first half of bench

The resevoir and plumbing in last half of bench

The sump


I would love an advice or recommendations on what I can do to improve growth or even see growth in the frags I have and coral in general. Anything is appreciated, even if it means upgrading lighting or changing something. At least something to work towards to fix any issues I may not be aware of. Love this Canreef site but way too many "study breaks" spent on here. Thanks
