Well no one has replied, so I'll hop in here with my usual comment that all a plant needs is N, P, and K plus trace elements. You can get those in a sack of fertilizer from the hardware store. The only advantage of modern cannabis fertilizing regimens--and it's a significant one--is that you can adjust ratios over the plant's life.
General Hydroponics three-bottle FloraSeries plus their CALiMAGic Ca/Mg supplement is all I've needed to grow potent buds, but GH has a dozen other bottles they want to sell you. It's all a marketing scam to get more $$$ from clueless growers.
That said, the people who use silica supplements are enthusiastic enough to make me curious.
And if you're growing hydroponically, I suspect that cultures of beneficial bacteria can help to prevent root rot so might be good insurance even though they are expen$ive and have short shelf lives.
So a big NO to sweeteners here, but maybe other folks who have actually used them will weigh in and tell me I'm FOS.
Put your time, money, and energy into good lights and good soil and tending to your girls and no extra, expensive products in bottles with colorful, sexy graphics designed to appeal to stoner boys are needed.
I will now step off my soap box and go tend to my grow. Good luck with yours!
