Might be forced to switch nutes in the middle of my grows. Looking for advice.

I have two tents in flower that have been using Jack's 321 system. I'm starting to run very low on my supply of Jack's and my next batch seems to be held up in shipping. With the USPS chaos, I have no idea when it's going to show up.

I'm having a hard time locating some jack's locally and I may have to switch it up in an emergency. If that's the case, is there a particular line of nutes that would be safe to switch to mid-run? I'm about two weeks from harvest on one and about two weeks into flower on the other.

I really appreciate any advice!

If it were me i would finish the one with Jack's and start using new on the ones that just started . Grab a bottle of bloom from local hydro shop and try and match the numbers . Or worse case Ontario get a tomato bloom from any hardware shop
Mega crop has a new 2 part powdered fertilizer that is supposed to beat Jack's . That would work if u have extra cal

i switched to jacks using gen. hydro flora series “Heads formula” with no known ill effects. i don’t think it matters as long as the nutes are available the plants won’t care what names on the bottle.
