I am on my first week of flower and my pics are posted below my leaves seem to be turning yellow all the new growth is fine and green but I am not sure why my plants are yellowing its not the whole plant so I am guessing that its not a lacking anything I dont think it looks like nute burn since I did that before any other ideas.

My nutes are Ionic bloom soil since its my first week of flower last week I used Ionic grow soil with some Cal mag ( The soils total NPK was alot lower than the other products by this company)
on the bottle it says to run 1.8EC
I have been running about 600ppm-780ppms all my other plants seem to be ok with it

Temps are around 70-78 and RH is 38-52

It could be nute burn ... plants' need change during the first weeks of 12/12 ... combined with whatever the soil is still yielding.
Or it could be a pH-related lockout issue. More than one possibility here imo. cn
 
I see signs of Mag deficiency in the leaf color pattern and location in the yellowing leaves and tell tale odd brown spotting on others that tell me of Cal deficiency.

Would it be better to flush the plant and then build it back up on nutrients? I mean it stll seems to be growing at a good rate

I don't think you need to flush. Just water for the next week or so with plain water. If it was nute burn, it should even out. If it doesn't, suspect deficiency or lockout or some other sickness. cn
