I thought that these nutes had Ca/Mg? I have to check that. I used about 1 1/2 gal. RO to flush each plant with. They are in 10 X 10 pots. I will test the run off. To do this correctly, should I pure more RO through and collect the first runoff drainage and test?
Just popped the worst one out to check out the roots. They are a little bound not to bad though. I'll put in larger pots tomorrow. Bad thing is I have to use the Organic MG again. Anything I can do to add to this soil besides perlite? Lime?
