What to do with a 25lb bag of Jack's 7-15-30

[grow-pro]

Have a 25lb bag of Jack's 7-15-30 as well as a 25 lb bag of ammonium calcium nitrate and some Epsom salt. I will never use that bag of 7-15-30 and bought it years ago by mistake. Any suggestions on how to supplement it and use it as a veg and flower fertilizer for soiless grows?

You mean 7-15-30, not 17, right?

That looks pretty similar to their 5-12-26 part A nutes, but with less Mg. Maybe you could add a bit more Epsom salt to make up for it...?

Bad typo on my part will edit now. Thanks for the catch! yea I was thinking that. was wondering if it would throw something else off but thats probably what Ill end up doing.

Too much sulfur is not a huge deal in soil, it can lower the pH though. Not sure about soilless tho...

Just add some calcium nitrate and use it in flower. It's close enough.

You can run it 3-2-1 and it will have a good profile for the major elements. Jack's Finish is missing the elevated micros to be used as a base salt, but you can get a small 500g can of those for a few bucks.
