I am currently doing two plants with Jacks. They have only recieved a single feed. Many on this forum use Jacks in combination with coco coir and perlite as a medium.
This is wise. Nutes are but a small portion of the requirement for large and potent harvests.
From Jacks. Do I just need to order the 3 part-- Feed, Boost and Epsom?
Part A then epsom then part b and you want to dissolve each part fully into solution before adding the next.
I use Cultured Biologix nutes. That is how you mix them also.
I volunteer at a grow store and I have customers ask for Jacks and wondered if that is all I need to order from them.
Part A, and Part B.
The A is the phosphorus, potassium, and micronutrients like magnesium, iron, etc.
Part B is the calcium and the nitrogen (in the form of calcium nitrate)
Epsom salts are widely available anywhere from Walgreens to Fred Meyer/Smithâs/Kroger in the healthcare aisles. Unscented pure Epsom. Itâs magnesium sulfate, which provides the magnesium Part A doesnât, and sulfur, another key micronutrient.
Just need Feed and Boost, no real need to get the Epsom from them directly unless itâs just an ease thing.
They have a million other products but theyâre not necessary to get a great grow in.
Thank you maâam. I will order all 3 for the store.
@Graysin my first feed with Jacks went well. The plants loved it and it was easy to mix, which I loved too! Thanks for hooking me up
My pleasure. Glad itâs working out well. I need to get the new bag of Part A out of my trunk. 
mine have been without for almost a week due to sheer laziness.
Truer words do not exist. Heâs guided me to some beautiful ladies. If i was single and not married⌠thanks Doc.
Should have added that quote to the post ontop if this one
Not alot you can do for lst till cple more nodes come up, she is still technically a seedling.
I just gently push over so the light can hit the little leaves underneath.
Ok thanks. Doc is one person I trust with suggestions
Let me ask ya, in your experiance do autos get any bigger/better in a 5 gallon over a 3 gallon bag? Or do you get more out of 2 3 gallon when space is limited?
There is the potential for a larger plant in a 5 gal pot. However, it needs to be in conjunction with a propper light. Youll get more from a single plant under a 150 watt light in a 5 gal then two 3 gals under the same light. (This isnt accounting for any of the other factors that contribute to overall plant size and resulting harvest quantity)
HLG 300L R SPEC 250W in 2x4 but can put in 3x3 if better.
Was just thinking about going 5 gallon this run but didnt know if it was worth my time being autos or if i should stick to 2 and 3 gallonâŚseeing what popular opinion is from past experiances.
