Some of the best fertilizers imo include Maxicrop soluble seaweed powder, Blood & Bone Meals, Bat & Seabird Guanos, Fish Emulsion/Hydrolyzed Fish and Palm Bunch Ash. We use all of these in both veg and flowering.
Mother's Finest hit the nail on the head. Guano teas and Fish Emulsion are my bread and butter, as well as bone and blood meal. But if need to use something that can just come in a bottle. I use a little Canna Bio-Flora. For Veg a good soil and a little Fish Emulsion from Bio Bizz is all i use.
There's so many good ones out there....I selected Bio-Bizz lineup due to a cost comparison of products that I KNOW are being used by the small "collective" I'm in. My results have been very impressive......light on the wallet and heavy on the results......just my 2c...........
im using CANNA TERRA VEGA AND FLORES iv bin told its a really gd product and its from holland so cant really go wrong!! found it on ebay for £8.95 a ltr which is the best price i have found!! happy growing ppl!!
