I bet your nutrients are getting locked up from mixing the B first.
The nutes in the A can react with the stuff in the B.
(That's why diff bottles)
Maybe that's why you see the pH Change.
Interesting.
i went through the same thing. chasing deficiencies(mainly looking like k deficiences), brittle stems, low yields, poor terp production. loosing clones.
mine was from multiple pathogens. fussarium root, fussarium crown, an another stem pathogen i hadnt properly diagnosed.( i did have a lab confirm both fussariums)
how i changed it was becoming cleaner in my practices. using pool shock to sterilize water at rez change, using latex/vinyl gloves when cleaning or transplanting, cleaning gloves inbetween plants. sterilizing scissors inbetween plants. scrubbing stakes & pots and any reusable product with bleach(pool shock). remove any debri ,scrubbed an sterilized with bleach(pool shock), then rinsed in a separate area with physan 20 an left to dry, NO final rinse.
Taking clones from healthy plants. Sterilizing rooms in between uses. Flushing drip systems with bleach an physan. Sterilizing the room with bleach or high grade hydrogen peroxide. Using a ozone generator in the room after takedown an cleanup.
attacking the fungus knats. cause they are a vector, they will carry whatever pathogen from plant to plant. sterilizing ph or other probes.
No recycling runoff, dtw. even sterilzing ph probes after checking run off. making sure run off wont come in contact with other plants. run off is another way to transmit whatever is the problem.
introducing beneficial bacteria at the right time, using actinovate.
worked for me. lotta work. lot of leaning. lot of learning. almost lost it all .....
hope u can work it out.....

I mix a concentrated stock solution of A and B separately, then mix that stock solution into an appropriate amount of RO water. First Silica, then A, then B, then additive (kool bloom - mkp replacement). I generally let the stock solutions set and mix overnight, with several bouts of shaking. I'm not sure this is it.
I saw a change in water quality. I used to use GH flora series and went from needing 2.4ml of ph down to 1.4ml of ph down, and alongside that change is when the loss of health of plants and continued problems started. Due to that, I was thinking there was something in the tap, maybe excess Ca or Na that is causing lockout. Since switching to RO and Eric's formula, things are greening up and coming around...
Thanks for the input
Definitely something I hadn't considered and sounds eerily similar. When chasing deficiencies I was dealing with very purple and some weak stems, reduced root growth, slow general growth. I could see it being a root pathogen. DTW coco and rockwool in my rooms.
They're clearing up a bit now where I think it might have been lockout from a tap water change, but will keep this in mind if they keep showing issues. My veg room isn't back to 100% so I'm inclined to think there's still an issue lurking.
Might hit a few things with actinovate or regalia and see how they respond with a few left as the control and no treatment...
Thanks gman and all who have provided input.
I'm going to stop cluttering up eric's thread now and will make a new one if any more questions. I think you've all gotten me back on the right track.

I stop spraying just because it will burn your pistils. I just spray preventatively anyhow. If I was actively fighting a bug or fungus I’d definitely spray beyond if needed.
How’s everyone been this summer? Been staying cool? It’s been nasty hot in the mitten. Not that I’m complaining because come February id give anything for a 95 degree day.

Thank you for the insight about the Regalia, now that you say that, I am noticing pistil burn.
Have you ever sprouted roots from petiole pieces? You might if you use Eric2028's method. Haha this is such an awesome protocol, thank you for sharing it. I didn't even do the method totally right, I was just practicing and used tap water instead of RO and my water temps were more like 80 instead of low 70s. This is day 14. I can't wait to see what happens with RO and the temps kept low.
Summer is going well for me! Those ACs are cranking in the bloom room! I tried the new MegaCrop 2-part but I'm not digging it and I'm going running back to Jack's.

A single dual 225 is enough to keep humidity in check in each room?
Maybe I missed it but what size A/C you running?
I'm setting up a 12k Gavita/Coco DTW room and can't decide if I want 3 or 5 gallon pots. I plan to veg about 6 weeks from rooted clones... in your opinion which size pot should I run.
Any insight is much appreciated....

Love the watering setup. How often are you watering in flower?
In those large 250gal reservoirs how do you keep the nutrients suspended... air stones, mixing pumps?
hey eric and all ya.... second time reading your thread.... lots of useful information.... what's going on we want new updates....
A couple pics of my last run. Everything is running as it was before, not skipping a beat! Ac’s been abused this summer tho.
2 quest 225’s per room and 5 ton ac per room. I run 5’s. 1.5 plants per light. 4 week veg. I’ve vegged 6 weeks and the plants just get too big, I always regret it.
Yep 2 airstones per tank. Blue air force pump.

Thanks. These were about 1.5 foot from the light. Some of the gg that were alittle taller showed some foxtailing.fiest picture unbelievablecannons... what is distance between lamps?
Ice cream cake. My new fav. 90% of what I currently grow.

This journal is awesome... really in the top 10 I've read and I've read many.
What's your opinion on a irrigation system using schrubbers? They spray 360 degrees, pressure compensating and the spread can be adjusted to different pot sizes. I think with a clean nute regime like Jack's along with prefilter and maybe some drip clean you won't have any clogging issues. http://https://www.youtube.com/watch?v=T56BsyDEGXk
You trimming all that by hand? Would love to know how you process and cure a crop of this size. I'm currently building out a 12k Gavita room and plan to add another 12k room once more funds become available. I don't see how I can get away with processing without using a machine for the majority of the lowers.

Thanks. I’ve never used that style of emitter. Just be sure to install a valve for flushing your system out, and use it at least weekly.
That ll help keep it clean too along with a filter of course and clean nutes. I like dry friction trimming. I use the trim bag. It’s great for rock hard nugs. Not so much for airy bud structure. With heavy pruning and defoliation you really don’t have “lowers”. Yes you have lower buds but they are not much different then higher buds. We use a green bros dry trimmer at the warehouse grow. Everyone seems to like it.
That ice cream cake is very popular. I prefer the wedding cake though, my current favorite. Trying to get the cut at the moment. I had a buddy who offered the ice cream cut, but his cuts are always contaminated.

MikeRoss, I tried the Shrubbler style sprayers and to get that nice spray it takes a lot of pressure. More than I have available. I have 80-90 psi before the fertilizer injectors turn on. After that I have 96 Netafim 2 GPH PC drippers and my system couldn't provide enough oomph. So I ended up just removing the shrubblers because they were just dripping out anyway. Added T's to the Netafims to make it 192 emitting ends so I could get better coverage of the substrate. The shrubblers do work great on my outside vegetable garden where I don't have so many emitters and the water pressure can make them spray out. One shrubbler can do a pretty good job covering one big 25 gallon pot with a tomato plant in it if you have a substrate that wicks the moisture well.

Right now I'm running big tubs with coco and I hate them with a passion. Four plants per rectangular 26 gallon tub. I had read about plants liking to grow with one another and was inspired by Jackmayoffer's coco beds, but this wasn't done right. The coco has compressed so it is now just about half full and thus a short and wide substrate, which is the worst for drip irrigation coverage (which is why I had to double how many emitting ends I had). It's staying sopping wet (I had a gnat factory before I dropped a mosquito dunk in one of the fertilizer stock tanks) because if I turn down the the watering frequency the top half gets too dry. I can't wait to go back to pots. Each tub has 4 Netafim drippers that tee off so I have 8 emitting ends per tub. The drippers are on 1/2 inch tubing in a loop to equalize pressure. I had originally intended to use Octabubblers, but Eric had said he didn't get even flow with those everywhere and I switched to the Netafim PC drippers. I love the drippers, they have even flow everywhere in the room.
