Thank you very much, that place is way cheaper even on the small 4lb bags and more so on the bulk bags.

After 5 weeks veg from seed 2.0ec, I started to see a bit of tip burn

Other than that everything seems good.

After seeing your post about the bump to 2.0 ec solving your deficiency problems I thought maybe I need to adjust mine. A day or two ago I saw the tell tale sign of a calcium deficiency beginning. Tiny little dot rust spots on a few leaves. The plants also did not look as vibrant as they should. I bumped up my ppm to 865 and watered all the plants with the increased strength. That was yesterday afternoon. I checked them in the evening before lights out and they were still sickly looking, but I contributed to that by reducing the power on the lights for about 12 hours. I for a second thought it could be light burn. After the plants drooped and wilted from the reduced light power it was clear the dots had nothing to do with the lights. I increased power to 60% on all lights. This morning I went down to check 'em all out expecting the worst after the sorry sight in there from last night. To my surprise every single plant in there is back to vibrant growth with all leaves pointing to the lights. I dam near couldn't believe it.

If not for your post about getting positive results from your increase to 2.0ec I'd probably still have sickly looking plants this morning. Thanks to you I'm back on track. Your plants look fantastic! Still jealous of that auto watering system :)

I like the idea of putting the rubber collars directly in the bucket lid. What happens to those rubber collars when the stalk gets big? My stalks usually end up as big as those collars.
They seem to just make their own space. They're inside 2" net pots. Never really noticed an issue.

I hope it works out for you.
I for one am done with Jack's.
Just a few days into flower and....

I made no changes to the feed so I'm stumped. Issues with mobile nutrients, but they're so different between the plants its hard to nail down the cause.
The tops look great still, but I don't want to push the issues any further.

I've been doing some research and have found others say they've had the same issues with Jack's. They love it, but can never seem to get dialed in on it.

For now I'm going back to the GH trio following their new schedule @ 1.2ec with another .2ec of Calimagic. I'm going to try floating around there for now @ 1.4 total and see how things progress. Possibly bump up to 1.7 if I see issues.

I am really frustrated though that Jack's isn't working out....
When it is working it makes some pretty plants.

looks like Mg on some leaves. if you run 321 vs 3part in a nute calculator, i wonder what the ppm of Mg is in each one?
@TintEastwood usually has all these common formulas on hand.
Yeah, I'm kind of thinking I maybe jumped the gun and could have tried raising my ph from 5.8 to around 6.2 to see if that helped.
That's one of the few things I haven't tried after trying to get Jack's to work over 3 grows now.

I may just give that a shot instead...just sucks to keep changing out a 30gal rez of RO... :)

do you use fulvics or humics? i've used both and i've been much more "forgiving" with my pH. i'm like low 5's to mid 6's now.
