Nutrient ? About switching nuits

So I’m currently using gh Flora trio, the “advanced” part. I’m currently in week 7 of flower growing hydro. Was wondering if it’s ok to switch to jacks 321. I’m almost out of diamond nectar and flora nectar, that’s why I want to switch.

I switched to Jack’s in the middle of a grow and had no problems at all.

Happy Cake Day.


Ok cool, also do you know how much silca and calmag to add to the jacks?

Add silica per the directions. Cal/mag is unnecessary with Jack’s. Use Epsom salt instead. Jack’s prescribes the amount of Epsom to be used.


I looked on Amazon for Jack’s 321, but all I found was Jacks Part A, Flower, and some other things. Is Jacks 321, and the Part A the same?

Jack’s 321 is Part A, Part B, and Epsom.

Ok cool thanks for the info

Damn I was going to recommend growgreenmi but the 2.2 pound pack of A & B is out of stock.

this will last a long long while

I have also bought Jack’s from Esbenshades garden center online. It has the 2.2 pound bags 23 - 25$


If I remember correctly eBay has much better deals on the small kits vs Amazon.

Yes, eBay sellers buy huge bags of it and then parse it out in smaller quantities. That’s where I get my 6 lbs of Jacks from. Very economical.

What are some best substitutes for greensand, feather meal and 5-5-5 npk fertilizer for organic growing, what i found is wood ash for greensand, fish meal for feather meal and no specific answer for 5-5-5 npk.

@pabloescobar , were you here before as @pabloescobarforever ???

Yes absolutely

This is a good sub for the 5-5-5 and organic.
Same balance of nutrients.
Only one account allowed so you may have to choose which one to keep.

Not available in my country and what about other alternatives i mentioned?

Do I have to keep guessing until I get one or are you going to tell me what country you are in?


See his name?? He might be in hiding. :laughing:
