New jacks user. Been using 3:2 ratio to calcnit. Mixed 122g/gal distilled of the calcnit Mixed 185g/gal distilled of the jacks to make a 50:1 stock. Been applying at 2.66oz/gal. This is about 1.5EC. Nutrient solution is dropping and I have yellow tips on the top of the plant that spread to margins and dark leaves that look blueish. These are about 2.5ft tall and just brought them,to flower. People told me nutrient burn despite a dropping feed. This was when I was at 1.9EC. Ive since lowered but still this issue exists. pH drifts 6.2 daily and is corrected back down to 5.6 daily. Not sure wtf is wrong. My 3 week veg plants are getting it now as well. They are at 0.9EC. The leaves are light green blotchy on these. These are almost a foot and are Bodhi Mountain Temple.
