It's about 2.1 after i add everything with ph around 6.0 sould I dail it back some and if so can I just add ph'd RO water to lower ec or do I need to make a new reservoir
Yes bro just dilute it in the reservoir that's fine.
Yes I'd dial it back a little I'd aim for 1.5/1.6ec deppending on the environment, the environment affects ec that's part of the reason for a stable environment.
Plants transpire water from the leafs the water evaporating over the day increases the ec, it's effectively getting concentrated (loosely speaking) but enough to have an effect over time if it's not rinsed away properly each day hence the importance of run off.
If you've a got dry environment the amount of water getting pulled from the leafs is more than an environment that's cool and humid, keep that in mind, if its hot/dry err in the low side and the opposite if it's cooler and humid.
I forgot to add in my 1st reply you've made a nice job for a 1st grow, well done dude.
