Sounds like too much to me. I don't use any 'zyme products as I prefer to run sterile.
I've been doing DWC since '01 using AN nutes but I don't buy a bunch of additives. Just the 3-part base which is the same price as others but has goodies in it others don't. Rhino Skin for silica and I use it from the start at low doses and not 2 weeks into flowering like it says on the bottle. It's buffered so doesn't raise the pH too much when you add it first to your water. The plain-jane stuff shoots the pH up to 10 sometimes.
For bloom booster I use Big Bud. Has a better P/K ratio for pot. 0-15-35, 20 aminos, citric and ascorbic acids and 10% sulfur to boost resin production. I've grown without it and the difference is very noticeable.
This round I also used the Bud Factor X and the last of a tiny bottle of Bud Ignitor. I got a 500ml bottle of the X as a free sample or wouldn't have had it and had bought the 250ml bottle of Ignitor a couple grows back and wasn't impressed enough to buy more. Might be some truth in the hype that all 3 work together to make a difference but not sold yet. If I could only get one I'd get the BB.
I'm just growing for myself and to share with a few close friends so my cost per oz for nutes is negligible. Electricity is 90% of my grow costs and I wish I could find that cheaper somewhere.
I also add a half dose of any boosters a week before I flip. Logic is that the plants are setting up bud sites and going through a huge growth spurt during the stretch and having them there helps set flowers better and faster. Waiting until week 3 makes no sense to me at all.
Here's a pic of my smaller Critical Mass I took a couple days ago right after light's out at the end of day 21 since the flip so exactly 3 weeks flowering. I think it looks a lot better than most hydro grown plants that don't get boosters until week three and as good as organically grown pot at the same time. With good organics all the things pot needs to grow big buds is already in the soil when flowering starts so why not have it there for hydro?
Lots of sugar forming on her already and the same with her sister and the two AK47 fems I have flowering now. 26" tall and that main cola is going to be phat! Growing in soilless ProMix HP which is similar to growing in hydro as far as feeding goes.
What are you using for water? I only use RO as our water is hard and the minerals in hard water can really mess up plants in hydro or pots.
