Alternative to jacks

Hello I have been using jacks 10-30-20 with good success, but was wondering if there was a one part salt out there that was more cannabis oriented that I should be looking at. People seem to like jacks 3-2-1 formula but I’m looking for a one part that’s going to mix easy. I gave maxicrop a shot at one point and I spent forever mixing.

How hard is it actually to mix?

Takes me 5 minutes.

Mega Crop has a one part but doesn't dissolve completely and can tend to be nitrogen heavy. Two reasons I switched to Jack's from it.

Jacks also makes the ro version which is one part. Just mix with hot water and it mixes super fast and easy.

Jack's tomato feed worked start to finish for me once.

I still prefer doing a "dynamic duo" or a 3-2-1 style feeding. To be clear I'm using "Jack's CLASSIC" in soil.

3(general)-2(tomato)-1(epsom) veg
3(blossom)-2(tomato)-1(epsom) flower

I love Jack's, I will never change.

GH MaxiGro and MaxiBloom dissolve almost immediately.

Jack's 5-11-26 has very little calcium in it, and a good bit of sulfur. they will react if combined before the calcium has a chance to dissolve fully in your solution, and precipitate to the bottom of your res as a fine black sand that will be useless to your plants. that's why they do it in a two (actually three) part formula, and why you need to add more calcium to the Jack's
