I'm happy to help if I can DG, but it's a learning gig for me too! ..reminds me, maybe I should whistle up
@MedGrower too, since he's helped me a lot in Sick Bay in the past
...yup, try 2-3 rounds over a week and see it if helps, but if you're still using the MC with the defc. girl here, I'd slip a little extra P in there too just to cover bases... Good on the roots! -that's huge... As for water T, getting that below 70F would be wise,.. higher T messes with pH and nute availability,...
I like that chart too, so I stuck it in the diagnostic thread! I prefer the attenuating bar charts best so you can see relative availability, instead of the often misleading "all or nothing" type graphics... in the real world, in soil that I've seen, the pH charts are a guideline, a generalization, not always spot-on accurate,... I've has acidic pots, alkaline pots that didn't show the respective defc.'s as predicted, or to the degree one would expect,.. lots of grey area, more so in soil/soilless though, MoG is right about hydro, it's much tighter and less forgiving!
In a pinch, I find those self-fill water machines make very good water, low ppm and at a much better price than buying jugs of Di,.... do you have some around, or an actual water retailer?
interesting chart MoG, thank you! Who's Mulder, and where did this come from? I'm trying to correlate it with the other things I have concerning this,.. but I need some clearer explanations about it,...and it's not exactly complete (maybe because it'd be a total visual clusterfuck if it did!)... So for example, Ca and Mg under the antagonism, what do they mean by "action of another nute"? Excess? I think so, because true, too much Mg can screw with Ca uptake, but visa versa
--so in theory, the arrow should go both ways,... looking at Ca and B, that's clearer, because our mate Skelly had over-limed a planting spot last season, and that plant had a bout of B defc....
--- reading under stimulation, an increase in N with mandate an increased demand for Mg, am I reading that right?
