Found it...
I've been dabbling with v+b for some time now, with mixed results. I ran 3 or 4 complete crops with the RO version, and 1 complete crop with the HD. I ran +life/size for the first few runs, but dropped it because of the sediment they left in my rez. I was mostly happy with the results,but I did have problems with the plants crisping up in the last 2 weeks in almost every run. Looking back on my notes, I see that I was running 1.6EC in most of flower. This on advice from HR. Actually, Chris told me to push the vegging plants till they showed overfert, then back it down a little. I can easily feed my plants(sourbubble) 1.6EC all through veg and most flower with no signs of problems, until the end. It's only in the last 2 weeks of flower that issues arise. When I push them, vegging plants won't show overfert until ~2.0EC . I've been carefully re-reading the thread, and seeing that most people are feeding well below the rates I used. I'm starting to think I've been overfeeding the whole time. I'm usually already on plain water for the flush when the crisping begins, so I had figured it couldn't be overfert. Now I'm not so sure.
A few crops back, I tried something different. I' ran v+b in veg thru week 2 of flower at 0.8-1.2EC. In week three I switched to PureBlendPro at 20ml/gal, along with 2ml/gal of Hydroplex. Both of these runs have yielded ~20% more than the v+b alone. Also, absolutely no crisping of the plants. I'd been thinking that the PBP was the real reason for improvement, but I'm wondering if it wasn't just the significantly lower NPK's of the PBP? Have I been "drowning" my plants in v+b? There wasn't any dramatic difference in smell, appearance or quality with PBP, just the increased yield. At first I just thought "cool", but lately I've been wondering "why"? I see several people having outstanding results with standalone v+b(dansbuds in particular). I'm also noticing that most everyone is feeding lower rates that what I've been doing. So I ask again, Have I been drowning my plants in v+b? I'm still cloning and veging with it(HD), and am open to flowering again with it. Just looking for some input from the community. I'm happy with the PBP too, but on the whole, the v+b is far simpler to use and store.
My current system is 4L pots with a 55/45 coco/perlite mix, fed with blumats. All my base water is 0ppm RO, the local tap is foul beyond belief. I'm growing my plants to 2-2.5' final flowering height in a very brightly lit, well ventilated 5x9 tent. I'd really like to hear from some of the more experience v+b users on this. I've still got 20#'s of HD and it's going to last forever just using it for veg. I do believe that v+b is a good product, I just haven't been able to get it to work just right for me.
your not drowning them EZ , your locking up the budset with an EC that high , its a really good idea to wait till the stretch is over & the budset starts before you reach your peek feed strength . other wise like i said , you can lock them up right from the start .
by lock up i mean the buds don't swell as much & they don't stack as well . they can look healthy & still be overfed . BTDT ! try it at no higher than 1.4 EC at peek feed & i'm willing to bet you see a difference in the budset & stacking .
theres not much difference in EC strength between peek veg feeds & peek flower feeds with this stuff .... .4 EC at the most . its not like other nutes wheres theres a nute for veg & 1 for flower , its the same juice, just adjust the feeds accordingly . by week 5 i'm backing off the feeds in prep for my leaching the last 2 weeks . coco holds onto nutes quite a bit . so by dropping the feed even half way , they're still taking what they want from the coco . untill its depleted of course , but by then you'll be feeding plain water till you chop anyways .
veg including clones get .5 to 1.0 EC , depends on the plants size .Thanks dan What strength do you typically use for cuttings? For veg? What does your typical progression through flowering look like for an 8 week strain?
First time I've seen that chart, but it coincides with how I feed from seeds/clones to harvest. Alas, I have no control over humidity
I guess we're using a different conversion factor.1050 ppm = 1.5 EC? That seems odd
Well, so far so good with using an airstone with veg+bloom v+b. If anyone has this question it'll be easier to search for now, it works fine no issues.
As far as ec amounts, I'm ebb and flow with hydroton, you'll need at least 950-1050ppm for starting clones.
600ppm (.85ec)

1050ppm (1.5ec)

Think I have this figured out again lol. Wish I could use .5-1ec but my plants went Hella deficiencies and crisped up (not nute burn but deficiency burn). Not sure if my system is different, just hydroton in 1 gallon pots in a flood tray with that said, love this stuff, glad I'm back to using it, maxi just couldn't one size fits all, all my strains.
alpha , stick to using EC amounts . your using a .7 conversion in PPMs where most of us use the TDS scale of .5 , this is why it gets confusing & we all should use EC .
1.5 for me is 750 , where for you its 1050 , dig it ?

Organic farmer, that's a great chart!! Super beneficial man!! Bravo!! Is that for the maxi crop!?????
Respect
