Modified Jacks 321 schedule

What is y'alls experience with needing extra calcium when using Jack's in Coco? Especially in veg? I feel like I overthink this, and often feed more CA than necessary, but I have had lots of problems in veg while trying to dial in Jack's 321. Does anyone actually thrive using the 321 ratio in Coco and using ro without extra cal? And to a lesser degree mg? I've struggled to dial in my veg mix. When I have tried 321 I had noticably better results after adding some calimagic lately, but seems a little rudiment. What ec are most people using during veg? I'm trying a little lower rh, accompanied by a lower ec. So right now I'm feeding at 1.4ec and just under 60 rh. I used to let humidity go up near 70 and I think it was causing some issues by not allowing enough transpiration
My tap water is 35ppm and I don't use extra calcium. I'm using 1.1 EC in flower in one autoflower plant and my outdoors have been happy with 1.6 EC starting flower. They've both been fed the same for a long under time.

I just did a grow with the Greengeans MKP Boost. The flowers look great and IDK if it matters or not- My purple stems almost totally disappeared, which he mentioned in passing, as why he bothered making a "Bloom"

Did you run the bloom boost formula from flip to harvest? What did you run during veg?

In my DWC, I run per gal-

1 teaspoon Silica every other week
Jacks A- 3.6 g & 1.2 g Epsom salt together - add
Jacks b- 2.4g - add

then I add

.8g Fulvic every other week, ( I usually do the Acid and Sand at the same time so I don't mix up weeks, one just the basic formula, then 1 w/ extras.)



I run that at 1/2 strength until seedlings go into solo cups w/ coco and perlite.

I run that 100 % from week 1 till about 4 weeks into bloom.
(My PH is high, but the only time I bother with getting it down to 6 is veg, flowers I hear like higher ph)

then-

about 4th week in flower I go to the MKP and more "B" less "A" same Fulvic and STOP the silica!!!!!!!!!!!!!

I've only done 2 grows with the "bloom" (Greengeans doesn't use the words "bloom Formula"), but to my eye and scale it's doesn't hurt. :)

Also IDK if it matters an iota but, Bye bye to my purple.....kinda pretty tho'

Interesting. I'm thinking of switching from GH to Jack's for my next run. What EC do you get with those numbers? I use coco/perlite also but I water frequently 3-6 times a day. I've read this should require a lower EC per watering

I've been running 4.2g base and 1.8g calnit with .25g potassium silicate that someone on here posted and it's been great. Comes to around 1.2ec which is great for multi feed coco

I'm running a modified, low profile DWC with the reservoir in the other room. The only difference is I don't use buckets, I have a large 6" deep tray with holes cut in the lid. My room is 6' tall so I have height issues. My plants hang down into the tray then spread across 42" x 42". It's worked out very well.

I don't modify jack LOL. I start at 25% for seedlings>50% for veg and slowly move up to actual 3g/2g/1g for the first weeks of flower and then start backing off as they mature to finish. Haven't watched anything from GG for years but I thought I remember him claiming that you could run full strength 321 from the start of seedlings all the way to finish. Which is just shit advice; careful of what you find on youtube there is much bro' science and stoner logic there.
I know this post is old as dirt... but, its the right topic and I have a question.

You state that you are/were using 3-2-1 at 50% for veg. Was that once a week or every watering?

I always feed every time I water. I also don't use some strict formula with my Jack's; start at 0.9g/0.6g/0.3g for the seedlings and just up the ratio as they get bigger and can tolerate it. I have been running Ace Seeds sativas over the last couple of years so never take them over 2.1g/1.4g/0.7g. I find that keeping the gurls on light feeding makes for a better high.
