Plants were getting way too much CaMg and I lowered it down to 3ml/gal last week so my grow had some nute issues. Any idea what is causing the weird dark green/light green stripes on my one plant?
It still looks like magnesium deficiency.. did you buffer coco? If not, that can cause your feeds to lose the available calcium and magnesium (among other nutes) immediately because of the charge the coco has if not buffered properly..
