Advanced Nutrients will give you, if not the best, one of the best results and yield if used properly. Don't listen to any goofs that blabbers about how AN is nothing but horrible watered down crap and complains about prices and marketing strategy. They are obviously growers (or bias growers) who have never used AN, used it wrong, or is just following the AN hater band wagon.
I've used Humbolt, GH, Heavy 16, Cutting Edge (also a good one), Dyna Grow, and Earth Juice (also a good one). I've grown indoor/outdoor, organically with compost teas and liquid organic nutes, and though buds tastes good, it's not as efficient in the growth rate and yield. Hydro is definitely not for me, I'm no longer down with paying electric bills up the ass and getting mediocre yield. Since then, I have switched back to outdoor and put all my plants under AN nutes. The price on anything AN is pretty hefty, but then again, you get what you paid for. I have yet to test out Aptus. This shit looks good but god damn it's expensive. I'd pay good money for good good nutrients and/or boosters that works, but as far as Aptus goes, I refuse to pay $2,000+ for a little 5 Liter bottle. In my current grow, I'm running new formula AN Sensi Grow/Bloom - Expert (incomplete) bundle.
For veg, I use:
Sensi Grow parts A/B
B52 (throughout veg)
I substitute VooDoo Juice for Root Excelurator from H&G (weeks 1 - 3)
Molasses (weeks 2-5)
Mexican Bat Guano (top dressed every other watering)
Bud Blood (the last feeding on the last week of veg)
For Flower, I use:
Sensi Bloom parts A/B
Bud Candy (throughout bloom)
Molasses (throughout bloom)
Root Excelurator (weeks 1-2)
Jamaican Bat Guano (top dressed every other watering for weeks 1-4)
Big Bud (weeks 2-4)
B52 (weeks 3-6)
Overdrive (weeks 5-7)
Flush everyday for the last 3 days of week 8 and no chemical taste
My schedule is - water (around root zone area) and feed (evenly across soil), every 4 days, then flush (last week of veg) for the transitioning of veg to flower. I no longer check pH because my tap water comes out at 7 - 7.2 and AN pH Perfect Technology drops it perfectly to 6.4 - 6.6. I use in low dosage and never go full strength. PPM is kept at 800 - 900 throughout the entire season. I don't use CalMag/Epsom Salt or any of those other stuff because I never really had the need to. Just keep this in mind, though there are endless selections line of nutrients, AN was designed for Marijuana and I will support a company that is not scared to support MJ. And no I'm not an affiliate.
