Might be a little late to do much about it now i would just plain water for a couple of feeds then back to the normal base nutes to finish the grow off. No more cal/mag in the mix plus ph run off in soil means nothing. testing the ph before using water so you have a basemark is a good idea.
Interesting, they haven't had any nutes for some time, I laid off them a few weeks ago as I had a bit of nute burn, a week later the calmag problem started. So it might be worth starting regular nutes from next water.
If I'm using organic nutes, do I still need to flush?
Thanks again.
