I have a 1 pint Add-it liquid fertilizer injector in line with my drip system for my 30 pumpkin plants. I've been feeding with Liquinox Grow 10-10-5 for the last 8 weeks, and now I have tons of vines.
I think now I'm supposed to switch to a higher potassium mix to promote and support fruit development, but I can't seem to find one in liquid form. My local Armstrong Garden Center has E.B. Stone dry fertilizers in every ratio imaginable, but they're dry powders and not water soluble (according to an email from ebstone.com), so I can't even mix them with water to use in my injector.
Broadcasting dry fertilizer is not likely to help at all, because the drip system will never get it wet.
Can anyone suggest a good high-K liquid fertilizer that's available by the gallon that isn't $100? Thanks!

Hey Waterbug. Hortman here. Potassium helps but phosphorus is what you need
for flower and fruit development. You have been giving them P and K all along. Just stop
giving them so much nitrogen which is just for green growth. Usually, soils are not deficient in
phosphorus. I would get a soil test done to check the phosphorus levels. If you are deficient,
then try this link. It is an organic site with liquid fertilizers. It has this liquid without nitrogen.
Good luck and take care.

I was having no luck finding a variety of liquid fertilizers until I found the hydroponics community. Now I see there's a lot of different stuff out there, but it's expensive.
I ended up going to Los Angeles Hydroponics on Tuesday and picking up some [url=https://www.hydrofarm.com/product.php?itemid=1687#tabs-2]B'Cuzz PK 13 14[/url] in a 1L bottle for $18.
It's pretty darn expensive, but the recommended dilution ratio is 1.5 mL/L, or 1:666, which is nearly 3x the dilution ratio of the stuff I'm buying for $10/gallon, so it's not quite as horrible as it sounds. Well, maybe it is.
But I'll try applying this a few times and see what happens.

1 thing I didn't or don't like about drip irrigation is the - water at a point. Sure it can spread out to a certain degree horizontally, but sometimes I feel the whole area needs to be drenched at times. Especially for plants that have vast root structure. When alkaline city water is involved, it worries me even more.
wow, that's some nice 0-5-5 fert Hortman! Peaceful Valley's got everything.
