High EC = Dropping PH?

I have a question.
I've had quiet some time growing in soil and it all went fine.
I switched to hydro about a year ago with well... Ok results. Pulled around 300-350g on 4x4 with 400 watts.

I am using the Lucas Fomula on RO water with Cal/Mg to EC 0.2
Top feed with clay pebbles watered every hour.

My big question is the EC.
I'm at Bloom Day 30 atm and in all of my grows I never made it to an EC higher than 1.2
As soon as I go higher my ph starts to drop and I have to bring it up to 5.8-6.0 with KOH.
I am using the troubleshooting guide linked to this post

I made some research and some of you are pulling crazy ECs/PPMs but I am wondering why it won't work for me?
Should I ignore the dropping PH and still go to 1.6 or so as Lucas recommends?

I am asking this because my plants could look way better like I say above and I want better results.
My Temp 25-27C and 60% RH shouldnt be the problem so I am wondering what's going wrong :s

Would love to get your help
Thanks a lot :)
