So could you not just add a small amount of brown sugar/epsom/myko for a little turbo mix?, would sulfur be ok on them?. If in small enough doses (aside from myko) could one feed it in small liquid volume amounts the day prior to a normal fertilizer feed ( that in turn may also wash out any excess sugar fro mthe day before).
There is a debate by some cannabis growers that S (sulfur) should be considered a MACRO nutrient..... I tend to agree for the most part. You can overdo it but, you have to pile it on kinda hard. K is under rated and under utilized for cannabis in my eye's. RM3 preaches from the same book as I, on that.
I sort of think your attempting to over think some of this.....Anyway, The amounts of sugar I use in the Mg and K sulfate formula's are delivered by now more then 20 ml from the gallon of concentrate you make, at a time. To a gallon of nutrient mix ... So sugar or carb amounts are lower then most think. That is quite enough to support bio health....
@vostok
I'm familiar with V's idea. Not really a fan of it in practice..... Feed the soil (bio's) and the soil feeds the plant,,,is more my goal.....
It's what works for me. Before you ask,,I'm not a fan of Honey in nutrient solutions...It's the antibiotic ability of Honey that puts me off. I'm told by some that it still works ok. But, I still have my "druthers".
Another thing to consider is. Most carbs are given in nutrient solutions by the nutrient companies. So root system bound they are.. I must say too, "I" have not tried any foliar applications of carbs.....just rubs me wrong. yeah I'm old but, it's that "druthers" thing again.
Many folks find differing ways to get to the same place. They all work and have become familiar with the "hazards" along the way for each. Some shorter, some longer. If your reaching the goal and not "loosing" anything along the way....Then it works...
