Morning Bill! I appreciate you so much for allowing me to post here. I'm going to copy you paste the last message.
But back to business-
Your coco washed and buffered pre use ?
What did you flush her pot with?
What ppm are you feeding 1100 ish?
What about nitrogen are you light in your mix or is she just not uptaking it ?
Are you putting your calmag in the water first and mixing well then letting sit for 15 minutes.
CA dream is 6 weeks in veg. I did pre wash and charge coco before planting. From seed to plug, to final fabric pot home. Photo seed.
PPMs have been up to 580 going in. Then noticed the yellowing leaf margins, purple stems. Thought maybe she was lacking nutes so I added a small extra bit. Ppm was then coming out around 875. Nothing changed so I checked the ph out and it was 7. Figured then it was locked out. Gave a good flush, about 4.5ph and still was coming out at 7.
So came for help be4 I killed her.
Calmag goes in first. I use General Hydroponics Flora series. Only thing I haven't done was let the mixture sit. I usually mix and dump. Thank you again for your willingness to help!
Good morning my friend
@W00 Hope everything is going good.
So first thing you should be closer to the recommended schedule for GH nutrients.
She is starving not locked out.
Bump your ppm's to 1000 right away and see how she reacts.
Your feeding every day yes?
Full nutrients every day with cal mag first, give it at least a few minutes.
Cal mag helps with uptake of the other nutrients when given properly.
I'll post a chart.
No plain water anymore
Ever.
Always nutrients at
5.8 that ph is vital.
Always make sure you get run off every time you feed.
GH has lots of salts as long as you get a good runoff you will never get a lock out caused by salts.
Do you use potassium silicate?
I used 1/2 ml per liter in water in all 50 girls once a week.
As soon as they were in a pot.
Fantastic stuff, I highly recommend it. Asap.
There are a few other things I used if you would like I can list them aswell.
You should be doing something for the roots, it's very important aswell.
Feel free to post update pics and ask anything anytime.
I run this thread under plant photo's so as long as it's pot related it's good.
And seriously any questions at all no problem.
One more thing maby 2 did you was and buffer your coco yourself and if so with what? Any perilite?
Oh and stop reading your runoff, you will chase your tail in circles.
Concentrate on what's going in that's the important part.
Ok list of order of nutrient mixture.
Stay safe
Bill
Ikr the waiting game is always frustrating. 
Spring definitely comming!
