I think I've run into the exact same thing. With hps I ran around 75F/55RH. With these plants I've tried to keep a 1.0-1.2 vpd running 80-82F 65-70RH.

So I've been vegging with Jack's and the plants love it. But then keep throwing deficiencies randomly. But the new growth looks great. I don't now what to make of it. Switching to floraflex for flower and hope they straighten out. But it's strange I've been vegging them for like a month like this on Jack's and they can't get their act together. I am using the Jacks Tap. phong to 5.8. Let the res drift up to 6.2 before correcting down again. My tap water starts at 0.7 to 0.8EC and I add jacks up to 1.4EC usually. Feed every hour for 2 minutes on 1/2gph emitters. 12 times during the light cycle and then off for lights off.

Those are the same issues I was seeing running 1.4EC with RO water. Nothing would clear up until I hit 2.0EC.
I would suggest raising your EC way up.

I had those issues when i used Jacks Tap version.. i ended up going back to normal jacks. Other have had better results though.. I would start the ph at 6.0 and let it drift to 6.5ish then adjust.
P.S. and a bit more EC at smoke said

For comparison
The Tap has micros, I don't list them. (No Ca, little Mg )

The pdf file at their website shows jacks321 is,
"A" 3.79, cal-nit 2.52, epsm .99
Slight variations in information?

holy crap! that's high to start with.
which did you get first: the tip burn or the Mg deficiency?

I think my comparison chart is based on...
3.6
2.4
1.1
Same ratio. 321
Amount depends on your target EC.

I i was scared to do high EC just upped to 2.0.

have you ever tried foliar with epsom in veg? or just adding 1gram of epsom per gal?
i run the jack's RO with well water and will get a bit of Mg issue occasionally , never Ca but 1g/gal of epsom fixes it right up.

have you ever contacted JR peters? i sent in my water analysis to make sure nothing in my well water would interfere with either the Tap or RO formula. then they got back to me.
i wonder if something in high quantities in your source water is interfering with Mg uptake??

Yes I do foliar Epsom. But it annoys me that I can't just get a nutrient that has everything. Lol. Also I'll try adding Epsom to res. But the tap says it has some in it.

the good thing about epsom is 1. super cheap and 2. the sulfur in it for smells in bloom. but i get your point.

Not adding mag. Because the tap version I use says it has some. And then I assume my tap water already has some cuz the EC is so high.

Yup... that's the same issue i had with jacks tap formula.. i even emailed jacks and they told me that it should be fine.. it wasn't
Add some mag and be happy.. That's also why i went back to normal jacks.. I will say though the tap version dissolved crazy fast.Problem with a tap version is, everyones tap water is different, my area has some of the best tap water in the country which means it has almost all trace minerals removed, they can't make 1 version that covers everything. Epsom salts cost literally like $3 for a few pounds at any drug store...
Just to share what i do that works for me is i mix 4gal of water when i do nutes (i top my 2 plants when they get about half way down the sight tube)
To 4gal i add 14,4g of jacks, 4.8g of mag, 9-9.5g of cal.. then add some AG and PH. I don't get insane about being super accurate but get close to those numbers.. the plants will tell you what they need after a day or so. If i'm in flower and a week or 2 out i expect yellowing leaves and some scavenging of nutes by the plant but have never had anything happen that made me worry.

It's also very forgiving. I run 2 grams per gallon on some of my mixes with no ill effects whatsoever. There is another guy in the forum who runs it much higher even than that.

I thought I'd stop by to provide an update on the foliage problems I was having. I wasn't sure at the time what was causing it so I immediately thought it was my fertilizer. It was not. I have spider mites. Bad. The problems I'm having with my plants this cycle and last had nothing to do with jack's. Russet mites are awful. Already had to toss 2 plants. Heartbreaking. Me and jack's are still getting along. A strawberry cough I've got going that gets jack's is looking phenomenal. My clones that are in a cloner with jack's right now look great. 1.8 ec for me. Fuck mites.

I've been rotating forbid, avid, and floramite every 3 days for about a week and a half now inspecting leaves the following day after each spray down. The plants have all been recovering nicely with new growth no longer twisting and no more rounded leaf tips. I also learned in this process if you see burned leaf edges and you know for a fact your fertilizer mix is correct you need to pull a leaf and check it under a scope. Mites love the leaf margins and veins for feeding and egg laying. I observed almost zero mite eggs in the center of very large leaves. Go to the edge and it's spider mite egg armageddon. I checked 10 or so leaves all with the same symptoms of burned edges. All had extensive mite eggs on the leaf edges.
I tore off every single leaf with burned edges then hosed 'em down in floramite @ full strength. Full hazmat suite & respirator of course. I mop the entire basement with bleach the night of spray then I use a pesticide only mop head to bleach out the grow room floors. Soak 'er in bleach for a day afterwards. Every morning I wake up with a fear that my garden will be decimated and today I finally feel relief. Every single plant is reaching for the sky again with fresh new foliage bursting out looking healthy and lime green as it should. I tore of a couple leaves from the most troubled plants and I had to look hard to find even 2 or 3 eggs whereas before I was finding patches of 20-30 eggs. The difference is incredible. I'm continuing the same spray regimen until they go into flower in 2 weeks. Then I'll switch to spinosad and venerate every 3 days for the entire flower cycle.
Jack's is doing fantastic! Here's a picture of the ladies back in action:
Blue dream just jack'n it:
The whole room. A much smaller flower cycle this next run. I lost a lot of plants to mites unfortunately. It's been a hell of a learning experience and it won't be something I'll let happen again:
Below are 2 strawberry cough's planted at the same time. 1 is in coco and 1 is in soil. Is that an incredible difference in size or what? I don't think I could afford to grow in soil with that kind of growth in coco. I'll be using coco exclusively moving forward:
A throwback strain here. White widow. She was badly ravaged by mites. I'm impressed she's making a rapid turn around. Super stanky strain:
Nursery a:
Some blue dream and god bud clones. I lost 5 or so cuttings to mites not to mention all 6 of my gg#4's. That shit hurt. As the plants in the flower room recover and bush out over the next 2 weeks I'll take another round of cuttings as the mite situation will be resolved by then. I'll continue treating the clones though as if they're still there. No fucking around moving forward. I'm a mite wrecking machine from now on:
Jager. She's a monster but smells like black licorice. Nice potency and very smooth but I'll be processing all of it as hash rosin:
Bruce banger. She was almost dead before the miticide treatments every 3 days. I can't believe she's still alive. Unreal man:
Blue dream bushing out loving life:
