That's completely untrue sir. I use the same formula from clone through flower. 1.65 EC. May I suggest you switch to a professional fertilizer like jack's 5-12-26 with epsom salt and calcium nitrate? It sounds like your current fertilizer isn't satisfying your needs.
I just mixed a rez and realized were @ the exact same readings.
I'm using 110/30/52g- a/ep/b per "can" for flower. Ph 5.8 :)

That's beautiful how you have that setup. Clean and efficient. Aren't those dam trash cans the best reservoirs? I don't want to automate my flower room, but man automation in the veg room would be lovely. Or even just running drain hoses to a condensate pump like you do, because dealing with the run off is really more of a pain in the ass than hand watering them. If I only did grommets and drain hoses on all the drain holes to a condensate pump in the flower room plumbed to my sewer drain I'd be on cloud effing 9 man! Right now I'm pretty laser focused on completing my flower cycle before I have heat problems. I've never ran the flower room with this many watts before during the warm months. I'm not quite panicking, but I'm walking at attention every minute of the day until the cold front moves in tomorrow. I literally start my AC on dehumidify mode 45 minutes before lights on which spits out a ton of cold air in the flower room while dehumidifying just before lights on. I got it down to 68 or so. Hour later I'm at 81 and stable. That gets me through the hottest part of the day nice and easy. I have my HVAC setup to pipe in cold air from outside still otherwise I'd just crank the portable AC non stop. Right now all the portable AC's hot air is being dispensed into my unfinished basement area. It's 82 in there now. Fuck :) What can ya do? I can't wait for my new LED's to arrive. Those HID's are effing gone as fast as I can get them out of there. When it comes time to replace the 600's I might do 2 more 660's. No energy savings, but I'll already be saving $200/month just removing the two 1000's and the AC not running as frequently if at all. The vision is five 660w panels, a 450w panel supplemented with two 100w 3500k COB's, and a portable AC cooling the room as needed. They're manufacturing my new two new 660's right now in 3500k lm301b ships with 660nm and 760nm epistar reds and mean well drivers. I should have them via express sea support freight within 4 weeks. I won't even be done trimming the next harvest when they arrive, so the timing is perfect. I could have had them in 10 days via ups express for $200 more. No thanks. Sea support freight sounds aye okay to me ;)

$695 and change for the two 660w qb's with shipping. Got 'er done on the cheap and this is my 3rd order with this company through alibaba. Great people, products, service, and prices.

Check out what jack's is recommending for boosting at 18:35. Good info.
Checking out the video now. Just for fun I'm going to try their bloom booster next flower cycle with a strain that I've grown many times and am familiar with. If I notice a positive difference I'll say so. If not I will say so also :) The recommendation on their feed chart is 1-2 weeks so if I ran it for 2 weeks that could amount to 14 feedings with the bloom enhancer as most of my plants drink daily once they enter the flower room. That's certainly enough exposure to have an effect. I don't have any interest in trying their clone formula though. 3-2-1 works excellent for clones. I'll come back and chat more after I watch the video. Thank you by the way! I love any informative videos I can watch about Jack's fertilizer.
 
I'm also going to do a side by side to see if it makes a difference. I'll keep you guys updated. My theory is that it won't change quality but perhaps faster flower setting, shorter plants and maybe a little higher yield due to the fact that flower formation occurred earlier. I'm loving the fact that my water is clear. It's so nice. No more flora nova crap on the bottom of my res or stupid red dye in flora series.

I think you're on to something there. The sudden introduction of a healthy dose of MKP, which is what jack's professional 10-30-20 blossom booster mostly contains, for the first 2 weeks of flower could rapidly accelerate the flower set process. With that the flowers have more time to develop, thicken, and ripen. Your theory seems aye okay with me. I'm actually pretty excited to give it a whirl. GreenGene, one of the first big promoters of jack's 321, used MKP in his jack's regimen. If jack's and GreeneGene say to use it you've got my attention loud and clear :) I'm looking forward to comparing results with you down the road as this little experiment unfolds.

I've been thinking about adding a 3rd reservoir for this exact reason. It seems each time I move a plant into flower I get a few deficiencies after a couple weeks. I've tried raising part A to compensate, but then I see signs of burning on the plants over week 5.

I'm thinking a 3rd reservoir with the booster added feeding them for the first couple of weeks after flip just might be a solution...

When I was running a higher EC around 1.8 I noticed burn on the foliage. Dropping to 1.6-1.65 seems to have solved that problem. Let's run it man. We got 3 of us trying this experiment out. There are some guys that swear by 600ppm start to finish. Just for shits and grins I'm going to run my next clone tote at that ppm just to see what happens. If there are no deficiencies then why not, right? I'm too afraid to try that in my flower room, but I'll test the waters on some little ladies that have less value :)

I'm also going to look into their finish formula. I'm so dam impressed with the remarkable improvement in flavor and burn qualities of the blue dream I recently harvested that I'd try just about anything Peters suggests. Their fertilizer grows fantastic tasting hydroponic flowers. No more dark maxi ash. Feels good patronizing a great company like Peters that really care about their customers and the plants they grow versus the other guys. No marketing fluff. Just great products.
 
That formula has a lot of nitrogen and even potassium. I think it's a general use booster. Phosphate is the main driver to supposedly turn on flowering genes. Check out the description on the 5-50-18 bag.

Yeah, wrong one for sure. I canceled and have a 2.2lb bag of the ultra violent coming 11-15th.

I got mine all as cuts from either Purple City Genetics or Dark Heart Nursery. Wedding Cake is the jbeezy cut, Slurricane is Cowboy's cut, GG4 is Josey's, SLH is Franco's, Dosido is the "norcal cut", Runtz is the Nick Runtz cut. It's great to be able to get these cuts out in Cali for $20 a pop. There are tons of other cuts I'd like to try too, but only have so much time and space. If anything I'm trying to eliminate cuts from my garden.

That sounds like a great problem to have bro. That’s fucking amazing. I looked up DHN and damn they have a ton of great strains. This might be a stupid question, but there’s no way to get a cut shipped?

I don't believe that they ship. A road trip in a rental car is pretty cheap these days though. You could come out to Cali and get all the cuts you want for cheap cheap.

Are you planning to use the 5-50-18 for 1-2 weeks at the 12/12 transition? That's a very interesting formula! I'm pretty certain I'm going to order their finish formula today. I want to hear the specific benefits so I can better understand how the product will help versus finishing with the 321. That 5-50-18 must be popular because growgreenmi is sold out :)

Just emailed this to Peter and am awaiting a response:

Hi, I'm currently using your 3-2-1 system with great results growing cannabis. However I'm interested in hearing more about your 7-15-30 finish formula. Can you tell me the benefits of switching to the 7-15-30 finish formula for 1-2 weeks at the end of the flower cycle versus finishing with the 321 system? Also, what are your thoughts on using the UV 5-50-18 formula for 1 week at the 12/12 transition instead of the blossom booster? It seems some growers are opting for your 5-50-18 formula instead of the blossom booster. I'm curious what the pros at Jack's think. Shoot me a line when you get a chance, and thank you very much for your time and expert advice.

I would love too bro. It’s about a 20hr drive for me so not terrible. Wouldn’t the clones die on the way? Also, with clones you can still get either sex right? Probably better to buy a few of each?

so im using Jacks RO formula with my tap water which is supposed to be the same 3-1-4 NPK as Jacks 321 except its a 1 part according to jr peters

everythings healthy but I did run into some phosphorus deficiencies in the beginning of flower. leaves turned purple. also had some calcium deficiencies along with it.

u jacks 321 guys running into this problem too? i ran jacks 321 for a run a yr ago but i cant remember exactly what happened. just got tired of mixing so many powders so often.

im thinking of trying the blossom booster 10-30-20 for weeks 1-2 when they start budding but it has no calcium in it at all. so idk how that works exactly. their feed chart doesnt mention having to add cal-nit with the blossom booster 10-30-20
