I no longer run my P that high, but things could change down the road. Thanks for the heads up.
I no longer run my P that high, but things could change down the road. Thanks for the heads up.Thanks Cap, I've been running Jack's Hydro Herb at 3.0 grams, 1.5 grams of epsom salt. After week 3 I switch to bloom booster for one week and back on the hydo herb till the end with no flush. I love your work and Snowblind. I'm going to run your mix and see if it makes a difference. I love your roots, whiter than a new pair of socks.
Have you played with Custom Hydro's PeKacid? One gram per gallon yeilds 69 ppm P and 44 ppm K.
Using jacks 3.7-2-1-.14cacl2 at 80% with raw ocean water for bennies in a diy under current ,the ec is 3.0,it's 1.8 before i add sea water there has been no touble yet i tried running at 1.2 was not working well . here are a couple of pic's at 33 days. i don' see how you can run jacks full strenght and keep ec low. i only use 1 gal sea water to 70 gal nute solution.What's up Snow? I run 3,2,1 thru week 5 at full strength. weeks 6 and 7 I drop to 50% strength and add moab at 1 tsp per 5 gallons. Then back to 75% strength for week 8.
All on a 9 week strain
i'm not top feeding just using diy uc i go to the shore and get sea water tried testing ec of sea water and it is to high for my guardian tester to register a reading.You cant run full strength jacks and keep EC low, but jacks at full strength is fine for many hydro applications. The sea salt spikes the EC considerably, but this is not an indication that you will burn your plants, especially when topfeeding. I read soem studies that plants when being top fed can take an enormous amount of salt. Funny enough they can also take a lot less than a "normal" feeding and be great. Gotta love top feed DTW. At some point I will switch everything I have over to that.

do you use moab week 8 when you go to 75% and do you flush at all?What's up Snow? I run 3,2,1 thru week 5 at full strength. weeks 6 and 7 I drop to 50% strength and add moab at 1 tsp per 5 gallons. Then back to 75% strength for week 8.

Jacks 3,2,1 and fulpower at full strength is about 980 ppm on my bluelab at .5
Nice plants tconch
No MOAB week 8 flush week 9do you use moab week 8 when you go to 75% and do you flush at all?
Same here, 1.8 on my Blue Lab. I really love the 3,2,1. Getting ready to go into week 6 on a 9 week strain.
sdgrower, when you run your base at 50% what is your EC or ppm when you add the MOAB. I've got a qt. of Black Magic I'm trying out during weeks 6 & 7. I was going EC my base nutrient to 1.0 and bring it up to 1.6 with the Black Magic. This is my first run with this bloom booster. Any comments or input would be welcome.
ebay. I couldnt find the one I bought but this one looks good:

No MOAB week 8 flush week 9
My jacks 3,2,1 ppm at 50% is usually around 500 or a 1.0. I have always had better yields if I use MOAB in week 6 and 7 vs Jacks 3.2.1 so I'm thinking Black Magic should help. I have not used it so I can't comment for sure. Please let us know how it worked out.
IMHO Jacks 3,2,1 is the way to go. I spent $110 on 25lbs of jacks and cal nit plus some epsom salt in January and have plenty left. I DTW in rockwool 100 plus gallons a week.
Thanks for the info SDNo MOAB week 8 flush week 9

Hey Cap,
Did you pick up the citric acid ph down from JR Peters? I have been using Jack's for the past couple grows with Earth Juice citric and have noticed the ph starts to rise pretty quickly (15-20 minutes it will go up between .1-.3). My water starts out at around 7.8ph and 60-70 mg/l, last test was 61 ppm CaCO3 for hardness. I have also been noticing what looks like a calcium deficiency in the last weeks of flowering and am wondering if the use of all nitrate nitrogen is causing my media ph to rise.
I have one room in Roots Organics soil and one room i tried H&G coco for the first time. The soil room is way chunkier but has more necrotic leaves, the coco room looks healthier but the plants (same stain as soil) did not chunk out nearly as well and stretched at least a few inches more than the soil room. Everything has been fed only Jacks and calnit. Any thoughts? I can try and throw up some pics a later tonight.

Jacks and Calcium nitrate alone are not sufficient nutrition in a coco environment; you need to be adding at least 5ml/gal of cal-mag, and in a high performance, humidity controlled room (especially sealed w/ CO2 supplementation!) you'll want to run 10ml/gal or even a little more to avoid deficiency issues. Also, in a high RH environment, you'll want to raise your EC (ppm) levels since the plants aren't transpiring so much.

Hater bucket! They get all crazed when the roots hit the swc layer. Makes me really want to get more volume of solution for those roots.
And if there is insufficient irrigation because of any failure point in that chain, the swc/dwc roots keep the top going as a backup for quite a while. I experienced this personally due to being a stoned dumbass on one day. Due to this safety feature, the crop dealt with a 12 hr irrigation gap really well. So stoked about that.
Too bad about the high ec being necessary, I hope to find a way to feed with lower EC than I have had to. Prob a different cultivar would make a big difference.
Thanks, its these little details that wind up making big differences. I like to keep a container of Cal-Mag for good measure although I've not had to use it since switching to Jacks's. Doesn't mean I wont in the future. Thanks again.
Just change the SWC to DWC. top drip overflow. Thats what I plan on doing eventually. each site will get 3 -5 gallons per day of top drip water. runoff will cause overflow. will have individual bubbling in each site with alita airline.
