Anyone ever try these pre-packaged fertilizer kits?

I am growing an autoflower. I have a FastBuds seedling, Crystal Meth, their mothership strain. I'm fairly new to growing and in the process of completing a space bucket. Medium is coco coir in a 2gal smartpot under 4 23w daylight cfl's. I need your guys insight about which fertilizers would be best for an autoflower.

Everyone knows about this Fox Farm line

FF is a mix of organic and synthetic, though I want full organic, preferably vegan as well.

This one claims to be fully organic by Earth Juice

And this one by Fire Horse also fully organic

Especially what works best for Auto Flowering strains. I'm also planning on getting some mycorrhizae for the roots. I don't have any experience using any fertilizers or feeding periods and would love some advice from you experienced growers. Anything helps, Thanks!

I have used fox farm for a long time. Works great. Can't tell you about the rest.

Watch the costs.... I never used FoxFarm Nutes...old timers told me the soil is awesome but avoid the Nutes. Haven't heard of firehorse.
Heard of earthjuice
..good reviews though.

I use Cutting Edge... But you should check out Humbolt County's Own..... Free starter kit... But you pay the $15 shipping.

I got some to review on our new site....

Peace

^ Are those organic?

Not ORSI or whatever. However they have a soil and hydro version. I will get with the rep and find out for you. I just started day 0 CES vs Humbolt County's Own. Put the beans in the coco this morning. Peace

For the MYCOS... I was using great white. I just switched to GS3 from Grow stone. It has Extreme Gardening premixed into the coco/redwood fibre. Check the GLoG for updates. My last log has some root shots at harvest. I also did not aggressively feed. I was seeing what the strain would do on its own...
