Thx for the help dk. Any advice or recommendations to battle my probelm. Just checked on my ladies and they seem to be doing slightly better. I mixed up a 5 gal bucket at half my normal rate (15-10-5 = 7.5-5-2.5)If the red petioles are accompanied by increased chlorosis of the bottom foliage than it could be a deficiency any of the major macronutrients aside from Ca and S. If the red petioles are not accompanied by lower foliage chlorosis than it probably a minor temperature issue, could be a sudden change in temperature or too high of temperatures at night.
The reduction in calcium nitrate is (anecdotally) suggested for improved flavor of final product, however your assertion that the plant requires less N during the last stages of growth is AFAIK, incorrect, unless there's been an over-application of N and an accumulation in the medium or plant tissue. As along as the plant is growing (increasing dry biomass) and producing the desired metabolites (both primary and secondary), N will be required in greater amounts over any other element aside from possibly K by small amounts. Always.
That being said, cannabis is way more sensitive to N overapplication than any other macro nutrient aside from Mg. Cannabis can handle huge overapplications of K Ca and S without showing any toxicity, while N will cause significant toxicity. Perhaps your assertion that you plant needs less N during the later stages is correct, however as I see it, if correct, it implies that your plant needs fertilizer in general as opposed to less N in relation to other nutrients.
As far as as following any specific nutrient ratio (e.g. N:Ca), I don't think ratios or relative values are all that important as opposed to the absolute amounts of nutrient applied. Again that being said, fertilization with N causes a softening of plant tissue and fertilization with Ca, B and Si causes a toughening of the tissue so the Ca:N ratio does have a very real effect on basic plant tissue strength, but following a o.8 ratio is more to keep Ca high if N is high so tissue doesn't soften excessively, not that you should necessarily drop Ca if dropping N. Those following Albrecht ratios often apply more Ca than any other nutrient and their plants do just fine.
Ppms came out at 650ish it normally is 1000-1100
Pretty much what would u do during this situation. What ratio do u run ur jacks.
Some plants "dolphin dicks" are loving the normal 3-2-1 ratio
