Jeg vil høste en WR om ugen, indtil uge 9 - hvor alt resten bliver kappet. Planen er så at markere hvert topskud med plantenummer, sort, samt dato for høst, og så gemme dem (de må ikke ryges endnu....dammit). Dvs. at omkring uge 10-10½ skulle jeg gerne stå med "5 forskellige færdigtørrede White Rhino toppe"

I'll weigh in with a bit of my experience. Most of AN's products are a complete waste of money, and i'll allow you to benefit from some of my side by sides if you'd like, as i've tested most of them.

Out of the list you have, I would completely drop the following products:
-hygrozymes
-humic
-b-52
-sweet
-liquid karma
-big bud OR hammerhead, and possibly overdrive.

Easy of course to say those things, now let me explain why.
First of all, since you are growing in a hydroponic medium, and are using non-organic salts as a nutrient base, you instantly remove the need for a sweetener additive, any sort of enzyme additive, any sort of bacterial additive, and most kelp and vitamin additives.

Sweetners are almost completely useless in hydroponics. These products are often sold as "flavor enhancers" and "bloom boosters". This is utter nonsense. The science is pretty strong supporting a very, very limited uptake of sugars into the rootzone, as the plant is designed to produce it's own carbohydrates via photosynthesis. The only benefit these products *might* offer a grower, is if a grower is looking for a food source to breed beneficial bacteria. These products will do zip, zero, nothing for your yield and flavor. In fact, they often have the adverse effect of feeding harmful lifeforms in your medium.

Enzymes are often sold as root zone protection agents, and some manufacturers go as far as claiming they increase nutrient uptake and plant productivity. I've not seen any evidence of this whatsoever. These are non-living chemical agents designed, in this case, and in cooperation with benficial microbes, to break down organic matter and make it more available to the plant. Great! Except that you're already using nutrient salts, which are already completely available to the plant and require no breaking down whatsoever. My one experience with enzymes was a disgusting, slimey res in one of my side by sides that ended up in a complete loss of a crop.

B-52 is a vitamin suppliment... i've been told its a sea kelp derivitave. Regardless, i've used this product in both a cloning environment, and in vegging/blooming plants. I did not notice any increase in cloning success vs my control clones, and I did not notice any increase vigor or growth in my plants. This leads me to believe, despite AN's marketing claims, that our cannabis plants *can* actually synthesize their own vitamins at an adequate rate. What a novel idea!

Fulvic acid is an excellent addition to your hydroponic nutrients. Fuvlic acid *is* humic acid. Do a little research here, you'll see that using both is a waste of money. Rule of thumb: Humics for organic soil, fulvics for hydro media. BTW, there are tons of ebay sources for very cheap fulvics... AN / GH and others tend to charge an absolutely absurd amount for their fulvics. I don't have the resources right now, but i'll be mixing my own fulvic acid concentrates in the next few months.

Liquid karma seems to be a quality additive for any sort of organic growing setup. Plenty of good stuff in there, and some people swear by it... but you're not using organic nutrients, so why bother? You'll find that liquid karma is really just a sort of swash mixture of b-52, fulvics, some vitamins, some micros, etc. Bottom line: You're running hydro. Skip it, it has very little if anything to offer you if you're already using salts and a fulvic.

Now, as for what I mentioned about your bloom boosters. Hammerhead and Big Bud are both designed as P K boosters for late flower. The only difference in these two products is the ratio of P to K. Some growers prefer a higher potassium ratio in their bloom boosters, and that's what Hammerhead is designed for. Using both would throw your PPM out of whack, and I think is a waste of money. So, choose one or the other. Experiment with both maybe with a strain that you enjoy and see what it reacts better to, and use that to make up your mind. As for overdrive, it's a decent product, but it doesn't have much more to offer you over just continuing to use your BB / HH until week 6 or so. It really is almost exactly the same. Just another AN marketing hype product, im afraid.

One product I would recommend is a silicate. It provides a mild benefit to stem strength and plant protection (and I stress mild). The mild benefit, however meager, is justified by the even milder price of these products. Dutch master, for example, is I believe ~30$ for a 1 litre bottle, and when you look at the dosage rates are something in the 10ml per 3 gallon range... very reasonable.

So anyways, I know that was a lot, but honestly the best lesson I've learned in the nutrient game is to K.I.S.S. Take all that money you're spending on additives and use it on your environment if you want real results.
