Personally I always keep it fresh but aerated and covered, I’ll keep it up to a week. I grow in 60/40 coco perl mix in my Autopots but 70/30 is a sufficient ratio. Jacks has everything you need but I start to add silica around the 3-4th week of veg and keep it in the mix throughout flower. Remember to add silica first before mixing in Jacks.

1…put a WaveMaker in the reservoir.
2…charts available on line. Use 3.6 gr part A, 2.4 gr of part B, 1.2 gr Epsom per gallon. Add silica first.
3…water daily onc established
4…silica is all you need
5…add about 25% perlite

@Myfriendis410 @SeaOhAreWhy ive always added silica first because thats what everyone has always said, just curious to the reason for this?

Adding silica first and waiting 15-20 before adding nutes ensures that the silica bonds with the water.
Awesome chart @Low! Printing and laminating as we speak

Glad you like it. I tried to get as much as I could on one printed sheet for my water station reference.

Looks like the group has you covered.
A good thing for you to do is check the pH of the solution each day before you water and see for yourself where it drifts and how fast. Then you will know exactly how your solution needs to be adjusted if at all.

I only have one question left. How many gallons do you mix that last a week?

can someone please explain how to use Bloom and finish? Do they get mixed in with the AB and Epsom salts or did they get mixed up on their own like Jack’s clone?

Sometimes if you dont tag people in on an older post it can get overlooked. Don’t be afraid to @ anyone. They’re awesome!

Morning, I don’t use bloom and finish so I’m no help there.

You really don’t need bloom or finish with Jacks 321, just run a little silica towards end of veg and through flower. The 321 is designed to run the same ratios all the way thru, though they recommend the first week of flower to use their Classic Bloom 10-30-20.

thanks that’s what I got was a 321. It came with bloom finish and Jack’s clone as well as parts a B and Epsom salts and I don’t know how to mix it
As far as i know you are good to feed the same 321 ratio from when you start feeding all the way to the end. Thats what im doing, week 6 into flower and they are doing great. Only other thing ive fed was molasses at week 6 and week 10.

According to the chart everything takes epsom except clone. I have all of these and id say the chart is pretty accurate. So for bloom and finish, you do not mix with A&B, just a stand alone like clone. And mixed with epsom

Mix part a first, stir until dissolved. I use separate jars to mix then combine. Second mix part b, then epsom. PH and feed, easy peasy.
