AN works pretty well, not as well as it used to though, before ph perfect. No you don';t need all the additives. I ran for years just using the hobbyist level package of nutrients.
the Hobbyist level consists of:
Sensi Bloom A&B
B52 amino acids and votamins - helps the plant uptake nutrients.
Big Bud - flowering supplement
Voodoo Juice - benefiical microbes and bacteria for the roots
Overdrive - end of flowering finisher - makes rock hard buds if your grow is going well. Can't take larf and turn it into rock hard bud, keep that in mind
I added in Sugar Daddy to this mix and
Great White Myco too.
Great White and
Voodoo Juice used together work GREAT. Add them in until the 2nd week of flower, I ran this in coco before they came out with the coco specific line, which literally saw ZERO difference with. If you're running ph perfect Sensi, get the coco specific Sensi grow and Sensi Bloom so you don;t have to mess with the ph, other than that, You don't need the Coco version of
Big Bud either. I tried it and saw zero difference.You might add in a little Cal Mag but i think you'll find very little calcium or Mg deficiencies running AN.
your feeding schedule is very important. in Coco, you feed, then water then feed, then water. Now, here's the trick - i got much better results when i fed less. Yes really. I would give the plants in 3 gallon bags 2 liters of full strength of nutes each feeding. I don't care if the coco was saturated or not. That's what they got. When I watered, I saturated the coco. When you overfeed with AN, like giving a plant 5 or 6 liters of nutrients per feeding, i got small fluffy buds. When I gave them 2 liters, i get big dense buds. this is strain dependent to a point. But Give it a try.
There are several places online you can order AN and it's almost 1/2 price what you'd pay at a hydro store. Amazon is one place. Discount AN is another. Over time i started adding in Bud Factor X and it does work very well. I saw a very nice difference using it. I do recommend AN's Cal Mag. It's the best on the market. I'm going to continue to use it even though I am trialing
Emerald Harvest nutes due to a personal issue I have with AN.
AN is also stupid easy to mix. I have 2.5 gallon gas cans. On that I fill with RO water. Add in 1 shot glass ( 1 ounce) of Sensi Bloom A, 1 shot of Sensi Bloom B and then 1/2 a shot (1/2 ounce) of each of the additives. No measuring out a ml of this and 2.5 mls of that - ain't nobody got time for that bullshit. Then i hand water the coco. have you seen the nutrient calculator on the AN site? you should check it out.
if you have any questions, pm me.
