I am approaching the end of my GDP clones and debating if I should use Jack’s 7-15-30 Finish the last week of feeding this time. I’ve used Jack’s 321 for a while, and although I’ve had Finish, I have not used it.
If you have used it, your pros or cons and recommendations are appreciated. Use longer than one week recommended?
If I decide to use Finish I have another week + or regular Jacks then a week of Fish then water only till harvest.
Thanks

@MidwestGuy @BigCat420 we will see what comes up. I used the Blossom Booster and had issues with it in the autopots. So a little hesitant to use Finish in it. The plants in the tent are top fed so I would start there.

@beardless be cool if that works for you because then i can have justification to go to my local grow shop and get the rest of the lineup lol. Just havent seen much on people using the full lineup yet

Looks like you’re gonna be our test subject for this matter and for the next person asking this question later on haha
I ran the finish line on this run weeks 7-9 with pretty good results. I have the regular and tap line of nutrients from jacks. 3 grows using just the tap and several many with 321. I started this last run with 321, switched to bloom for 3 weeks, back to 321 for mid flowering then finish the weeks 7-9

The only thing I use is MPK at transition. Sorry; can’t offer any advice.

Did you also run Finish through your autopot trays?
I checked your threads and couldn’t find mention of Finish.
Thanks

Thanks - got it. A year in the adventures of
to keep N and Mg level up?
Looking at it, Finish is all that much different than Part A 15-12-26

Wow I forgot about that run. Yes on the nitrogen and mag, it was recommended for the tap line bloom and finish nutrients. Not a lot of difference between the 321 base and finish make up. My biggest F up was 2 runs ago trying to get the almighty fat dense buds and started adding bloom boosters to my finish line and over did it on the PK and had horrible fox tails.

I think this one also came from one of Greengenes videos
Are you familiar with the one labeled Jacks Hydro 4:2 - only parts A & B without Epsom?
The basic 321 is well balanced compared to the rest. Lucas is pretty close
Not familiar but yes the original is good, mkp has its advantages for its boost but normal jacks is good
