I understand the pot thing.
I don't understand the difference between your veg and flower. Same soil right?
If that soil is good for flower why do you feel the need to add to it for veg?
Yes same soil I take the pots of soil clean the roots out and replant a new plant back in it. Then feed and with cal mag.
But there still seems to be a mag def. no matter what food Ive treid.
Im wondering if it is a lockout issue.
But now that u said its really easy to flush SI maybe thats what I need to do.
Maybe the best course of action would be Make up a light food and flush with run off till things stabilize. Which I haven't tried.
Hope this makes sense. Sorry not trying to lose the purpose of this thread.
