If I'm reading this right you were using Fox Farm then switched to GO? If that's right Fox Farm isn't 100% organic and GO is. This could be where your having a lot of your issues(PH). You probably have killed most of you soil microbes with FF. But this is just a guess.

Anyway man, your plants don't look to bad. Up your N slightly being that your in flower. Add a little bit of lime to the plant that has the calmag issue.

Honestly I know that PH has just about everything to do with lockouts and whatnot. But it seems that each plant is having there own issues. If things were across the board then I would say your dosing is off. I believe with the prior FF use then switching to organic you have disturbed the living conditions of your soil. This is my guess friend. I would A. Either plan how to use GO that fits you best for next grow or B. Switch to an easier nute regiment like Earth Juice!

Honestly I had a lot of PH issues with the GH line, then I switched to the lucas method and things were a lot better. Then I just chose to find the easiest solution when dealing with PH. That's when I found out about EJ. But there are a few products out that don't need PH synthetic or organic.

I hope things work out for you.
