252 LED array - dimming ?

[reeferdale]

Hi all,
I bought 4 of the meanwell HLG-240-48b drivers and I finally have 2 of them wired up to my LED array. I have 1 running 6 strings of 11 (66) XP-G cool whites and the other driver running 5 strings of 12 XP-E royal blues (60). This is half my led array. I have the reefled dimming kit (2 pots in the case). I have these wired up and when I put a meter on the pot outputs, I can see the volts go from 1 - 10, I also see the voltage change on the wire that I am running to the blue (+) wire of the driver. When I turn the pots up and down, the LEDs get brighter and dimmer but my concern is that each string is running about 600 to 1000 mA and I can not get them to turn down any lower than 600. I know I need to balance my strings but my concern is that these do not dial down to the 200 or 300 mA range. I do not think I will ever want to run these up in the 800 - 1000 mA range. Can anyone throw me any suggestions on why they will not dim below 600mA?
Here is the basis for my parallel wiring layout.

Here is a little more info
I have my driver leads running to terminal blocks. wire in , fuse, 1ohm 3 watt resistor and then out to the first LED of the string. I measured vf across the resistors and they are all over the board, 600, 800, 800+, etc. I know I need to start swapping some LEDs to get the strings balanced but it just seems odd that even when these are dialed all the way down, the vf across the resitors is never lower than 600 mA.

I have not measured from first LED to last LED and I have not measured the vf of each LED yet. I did not want to let them run that high and that out of balaance for long, plus it is almost impossible to work on them at 600 mA. I could post some pics of the wiring and such, just wondering if there may be something I missed inthe build. internal pot on the driver, etc.?
