It is interesting that the sugary supplements didnt help anything for him in hydro, I have noticed they can do more harm than good to the overall system. Its more about getting the balance of nutrients right so the plant sends sugar to the roots for the microbes to feed on rather than have the sugar in the water. 

It also turned on the light bulb on cal/mag toxicity for me, never seen it but I have seen K deficiency several grows and too much cal/mag can block K. Duh.  

Yes a couple of the commentators look like they are broadcasting live from grandma's basement and I really dont need to hear what they have to say and hey if you can reach them I say go for it, I am just not that bendy.
