Believe what you want. I use molases and candy. Work great for me currently running 4x 5 gallon air pots with coco and perlite (70/30). To be honest if youve added that much sugar to your res it stops pumps from working due to things being sticky. You've added waaaaaaaaaaay to much and prob a fucktard. A plant does produce carbohydrates in photosynthesis you learn this at like 10 years old in school what's your point? It's the additional carbohydrates you add that help feed your plant. You should be using mircobiolgy in your grow also which benefits from this. Raw do a nice version it's very concentrated can't remember the mixing ratio.
Added to this molasses has loooooads of other micro and trace elements. One being Calmag as mentioned previously. If your using coco and high powered LEDs you going to have some form of calmag problem especially if you're a little in experienced with LEDs. Why add more salt based fertilisers?
Here's a list of some of the key elements in molasses. Iron, maganese, magnesium, calcium, copper, zinc, potassium, phosphorus, certain B vitamins, and sodium. All of which are good for plants in the correct ratios. Molasses has also been proven to prevent salts build up which cause pH fluctuations......
There is also a tendency to say oooooo marketers make you believe that it works. To some extent this is true. However not to the level people like to think. You have to remember firstly they are regulated all across the world by various different regulators with different regulations. The products have also been researched and developed by these companies and every company has a version of. Also the market place obviously buys them and truely believe it works as people try and test these things every fucking day....... The products are still around and people are still using them with great effect. It has to be more using than not otherwise it not as it's not beneficial for companies to carry on producing them. Economics 101. Good saying bad workmen blame their tools. Same applies. You nuke them with nitrogen it's not biobuzz, AN, or Raws fault isit.
This debate is as old as hydro. People fuck it up and think it's the products fault. Same style of war wages on between flushers and non flushers, hps and leds etc.
Use the Lucas style approach of less is definately more and you won't go far wrong.
Another theory never tried it but there is alot of info on here about it is introduction of milk for enzymes if you're looking for other werid plant knowledge.
