Guys
I am going to give Jacks 321 a try for my next grow.
I have been researching their feed schedules and have noticed that for the one to two week period where Bloom Booster is indicated, there is no calcium present on the mix, just the 10 30 20 and epsom salts.

Now i understand the precipitate fallout issue between phosphorus and calcium when they are mixed together in concentration, so i will assume that this is why calcium is left out of the mix for this period of flowering.

For those of you using Jacks 321 and their Bloom Booster, have you noticed the absence of calcium to be an issue?
Have you found a way to add calcium to the bloom booster and epsom salt mix?

I know some do not use the bloom booster and just continue on with part A and part B to the ripening stage, and this is an option also.

Thanks for your thots.

Yup stick with one ratio start to finish.
The Doc Bruce Bugbee suggests ,20-10-20 @ 1.4 EC Start to finish.

Not anymore. Jacks now has 15-6-17 Clone, 10-30-20 Bloom, and 7-15-30 Finish on their 321 feeding chart. I guess they couldn't pass up the opportunity to sell more bags to cannabis growers.

As per the OP's question regarding lack of calcium, they're designed to be used with tap water which is going to contain calcium.

"The combination of the grow and bloom formulas utilize the good nutrients that are found in water sources with higher concentrations of Calcium (40 ppm Ca or more)."

When you have a group of growers beating down your door to buy products they don't need it only makes sense to oblige them. So many cannabis growers believe the more complicated it is the better it has to be.

that's what the founder of dyna gro said too. the growers wanted a bloom formula so he made one. but he's said all along that the foliage pro is the best for cannabis.

the customer is always right i guess
