I see many posts where people say FF Ocean burns plants, I've never had a nute burn with it. I have a theory , these people who claim FF Ocean burns their plants, are probably dosing their waterings with liquid nutes TOO EARLY. With the combination of the nutrients in FF Ocean AND adding nutes in with the water when the plant is still young...yeah..you'll probably see nute burn, but FF Ocean doesn't deserve the blame. I give either plain Ph'd water or worm tea to my plants for their first 30 days of life and I use FF Ocean soil exclusively. All I use for a nute feeding is Earth Juice Bloom. I never use a fert. with nitrogen either, as in a store bought bottled source of nitrogen. The worm castings and worm tea I use have just enough nitrogen to carry me through without having a severe deficiency as well as what's in FF Ocean.
I am a light feeder when using "manufactured bottled nutes" , even when I use Earth Juice Bloom I never give more than 4 feedings. My mix is this> 1 gallon container of my home grown worm castings and 1 gallon of perlite mixed into a 1.5 cubic foot bag of FF Ocean soil. Every other watering is fresh worm tea that's been brewed 24 hours. Around the 5th week then I dose with a weak solution of Earth Juice Bloom.
When I started growing back in 2007 I fried so many crops. I used everything from Miracle Grow Organic coil , Scott's , cheap-o no-name "watch-it-turn-to-mud" soils, ect. It took me about 8 months before I actually seen a crop go all the way to harvest and my first "successful" grow was with FF Ocean. It cost $108.00 with shipping adding in to get 3 bags of FF Ocean soil delivered to my front door. At the time I lived in Georgia and the nearest store that had FF Ocean was a 90 mile drive, so after that I found a plant nursery a few miles from where I lived then and started using Metro-Mix 300. Living in Colorado now, every grow store in every direction sells FF Ocean soil.
