fox farms tiger bloom is 2-8-4 so use something like that as a base. there are 3 teaspoons in a tablespoon. one teaspoon/gal would be like 6 6 7. but start off light and work your way up to that. Like a half a teaspoon first, see how they react and up as needed.

thanks bos is that what the numbers do change if you lighten the dose I also have fish fert liquid 2-4-0 would that do plants any good during bloom I know the fish fert during veg sure made them pretty and shiny they seemed to have loved it

If you want to try it out give it a go. You can always flush and start the fert over if your plants show you they don't like it. Just use standing proven flower ferts like tiger bloom and big bud and try to get the same N P K ratios. The only way you can find out what works for you is to try it.
