Are these nutrients suitable for flowering stage?

I'm using Canna Boost and Canna PK 13/14 with another plant food with these elements:

Nitrogen 24%
Ammoniacal nitrogen 3,5%
Ureic nitrogen 20,5%
Phosphorus pentoxide 16%
Potassium Oxide 16%
plus some other small amounts of other elements.

Is this suitable for indoor grow?

It seems like the total nitrogen is 24%, which is made up of ammoniacal nitrogen at 3.5% and Ureic nitrogen at 20.5%. I'm not very familiar with ureic nitrogen. I did some searching to see what I could find, but there wasn't to much information on it. My guess is that it's either derived from or is a type of animal urea (pee). If that's true, then it would require microorganisms to properly break down and I'm guessing its a slow-release fertilizer. I'd also be cautious about the high salts contained in it.

I'm sure you can you can make this stuff work, but keep in mind that most of the premium nutrient and fertilizer companies tend to use nitrate nitrogen and ammoniacal nitrogen. Urea and any other type of nitrogen is mostly going to be cheap filler piss and they usually take a while to break down. And high numbers like 20+ suggest its probably designed for lawn applications which love high concentrations of urea nitrogen. Again you can make it work, but anytime you mickey mouse things you'll really have to pay attention to how your plants react.

does seem a little heavy on the nitrogen. especially for late bloom.

Oh yeah, this is most def a Veg fertilizer, no question about it. NPK is 24-16-16.

i would say he could get away with it for veg and the first 2 weeks of flower. then he'll need to start adding the canna pk and boost.

Guys this was very helpful. I just have one more question. How much Canna Boost and Canna PK 13/14 should I use to my watering mix? The dosage written on the bottles or different (more?less?)? thank you.

Go to Canna's website for a custom grow guide ( http://www.cannagardening.com/ ). The exact amount depends on how your applying it and how large your container or tanks are. The general rule is the first week you mix 1/4th the first week, then 1/2th the second week then move on to full strength and adjust based on how the plant responds.
