they don't put enough to compensate you removing it all in r/o or distilled. His symptoms are clearly a ca/mag def.

looks to me like you had a nitrogen deficiency (even fading to yellow in lower leaves followed by chlorosis) and the beginnings of a potassium deficiency(brown spotting on lower leaves with a piney/olive appearance to leaf color) that was corrected 2 res changes ago and - if anything - your current load may be a little high on nitrogen(deep green, nearly blue appearance in new growth concentrated toward the plant top)

also, nitrogen abundance would be antagonistic to calcium, causing the recent calcium deficiency evidenced by the brown tips of those otherwise very green leaves

get an ec meter and your problems will be solved
meanwhile, i'd back off the nutes by a milliliter or so of whatever has the nitrogen in it and watch my growth

do you know how difficult it is to convince a plant to become deficient in a micronute without some underlying cause? like by sheer usage of that mineral? - ime near impossible

seen cal/mag def. enough times to know what it looks like. I looked at his pics and knew he was using r/o or distilled. He never told me that. Red stems and brown spots are a clear symptom of a cal/mag def. N def. would cause yellowing of the whole plant and wouldn't have brown spots. also N def. doesn't cause red or purple stems, but a ca/mag def. sure does.

i seen on there about crushing up pills sorry just no garden centers open here till spring and hydro store 75 miles away

i have crushed up B vitamins to promote root growth before and i does help so your idea will work... as long as you crush them to dust(use a credit card like the drug addicts do)! crush your 100mg calcium pill and use only half of the powder... dissolve it in some water a cup of water then feed your plant that. and i guess crush 25 mg worth of Mg and put it in your special cup of water with the calcium too. viola homemade cal-mag!! dont snort the powder lolz
