NPK 2-10-5 or 2-2-4??

Both would make good flowering nutes. Ideally, you would want something with slightly higher N for the vegetative phase, but if that is all you have either would work.
 
What brand are they? As long as you use them properly, in the end, it probably isn't going to make much difference. If it were me, I'd probably go with the 2-2-4 though.
 
I would do that as well.. . :)

with all the items I just added to this soil blend.. it is probably 40-40-40+ by now lol, much to hot to simply put a plant into.

best choice?

your 2-2-4 food is similar to the food i am using 5-4.6-9.6 for flowering yours is just less concentrated
not sure about the 2-10-5 , most foods i have seen would have the higher k ratio for flowering

i would go with the 2-2-4 it seems a pretty standard ratio for flowering

i heard a high P will make your buds swell up K is for foliage

this is a common mistake
it is more about ratios , you will find most foods increase both p and k, for flowering while maintaining the same or slightly less nitrogen

the two most used hydro foods in the uk, canna and vitalink, use 2-2-4 for canna, and 5-4.6-9.6 for vitalink, these are virtually the same ratio's of npk, its just vitalink is more concentrated than canna

if you round off the decimal vitalink values you will get 5-5-10
as you can see both canna and vitallink have the same ratio of n and p with 2x the value of k for flowering
 
no the 2-2-4. but that depending if youre using any additives. also i was going to give a detail answer but the skunkdoc as covered it it is a common mistake...
 
dats de one for flowers. Wood ashes are good for calcium, just sprinkle a bit around pots and let it water in....
 
Don't use epsom salt man. 90% of the time I've seen anyone use epsom salt it's ended badly. Check the back of the bottle they might even contain small amounts of calcium and magnesium. If not, you can pick up a small bottle of cal-mag for under $10 if you need to. A lot of time it isn't something you even really need at every feeding so even a smaller bottle will go a long way.
