Hello OHC
Click quote at the bottom and fill as much of this in as you can so we know as much as you do.
SOIL:
MiracleGrow seed starter
How long has this problem been going on?
you got me - it's been one thing or another since week 4 - this yellowing with the green veins has been the biggest issue but has repeatedly gotten better with calmag. The nute burn incident early on seemed to be at a halt. The tops all got burned around Thanksgiving and that seems to be resolved. This is a loaded question for me as I'm new, timid because of WW "nute sensitivity" and no experience.

What is the TDS/EC/PPM of your nutrients used?
I don't know what this is
What is the pH of the "RUN-OFF"?
last time it was 6.4 after a thorough watering - this time I didn't check it OR adjust ph after mixing nutes because a poster here brought to light the the new GO nutes directions say to NOT adjust PH after mixing - to start with adjusted water. The gist was that the organic nature of the nutes when interacting with the soil would adjust the ph???? I know - sounds crazy to me but I'm just a sheep.... baaah baaah.
