Yep. I mark my bottle so that I remember what the dilution ratio was and what to measure. (FNB 1:2 24ml/gal) (FNG 1:1 10-14ml/gal)if you made a 1:1 diluted solution, thus making it half as potent. wouldn't you just double the suggested amount to add?
If you have anything to strain, you haven't fully mixed it yet. You really don't want to leave anything in the bottle as a 'solid' as it affects the quality of your grow. If you're having clogging issues, look to your setup.also besides diluting and mixing with a paint paddle bit, I am thinking of straining the mix
I haven't used it for aero so definitely do a search for those that have. I do know that the mixed solution is just as clear as the 3-part so I don't see where you'd have any issues with it. You use surprisingly little per gallon, remember?
