Again you have amazing reading comprehension, I'm not telling anyone to do what I do. I answered the op what works for me.
Wow. I usually wait til they are established in my flood buckets for a week before going to full strength. Am I just holding them back?
No no no, you're a bad grower cause what worked for you isn't what he did!! (That's sarcasm for the extremely literate bunch that might miss it)
That's cause there are a million other factors that influence how hungry your plant is. How much light is hitting it is a major one, so is strain. Even things like humidity affect it. There is no wrong answer, there is what works for you in your environment with your genetics.
I am just starting out in hydro and I'm using jacks 3-2-1 at full strength, after the 1st week, and have some nice looking grand daddy purple at 4 weeks into flower. My EC is 2.4 -1200ppm (500scale). You are about half that? I'm sure that it is working for you, or you would adapt. We all want beautiful full plants. You obviously have some good knowledge and experience! But there is truth here.
Any/all strains?
All.
Totally, another factor is that different trace elements conduct electricity differently. So adding a shitton of one thing may not influence that meter as much as a tiny amount of a different trace element. Ppm readings from a $30.meter are abit of a crapshoot to begin with.
Yes an EC measurement is just a ball park figure. True elemental PPM can be significantly different. Also the EC isn't always linear depending on the element/s involved.
Would you consider giving jacks another try?
Probably not, I just get such amazing results from the GH and have been using it for so long that it's second nature to me. For me the cost of nutrients isn't a big deal. My real cost is electricity. Nutrients cost me about a grand per cycle (for both flowering rooms) and yeah I could cut that down to say 25 or 30% but I risk a crops yield and quality. When I am pulling 45 - 55 pounds per crop the cost of nutrients isn't a big deal for me. I just love the flavor I get from the GH, terpene production is superb. In my case, if it ain't broke I am not fixing it lol.
Jack's tap? Interesting , I Haven't heard of that formula yet, would you Care to share?..Or is there a thread/post on here for that I can check out?.thanks man
I actually just found one of your post explaining your situation with your tap being high in Cal. I had this same issue with my well water being too hard and screwing up many of grows because of it. I had no choice but to purchase an R.O system if i wanted to start without guessing what the 300ppm of start solution is actually (found out mostly Calcium, waters hard)..good luck I'll be following-
it's jacks' tap 15-5-20. i sent my well analysis in and Dr Peters replied with what she thought would be optimum. my well is much lower than yours; only 0.2EC
Do you add anything else with that? To me it looks low on Ca, Mg, S, Fe and the other micros; that's not going to work in my environment. Going to stick with my 321.
nope. got more ca and mg than DG foliage pro which is a proven cannabis nute start to finish.
I do not measure my ppms or even worry about it anymore. Years ago I read through page after page of the guys on here using 321 (and THC Farmer), I even played around with the nutrient calculator spreadsheet. Now I just try to read the plants (look for Ca spots, tip burn etc.) and adjust the strength. I have always struggled with Ca issues in my grows, could be the coco based soil and my QBs and COB lighting but Jacks 321 solved most of that. Was curious about the tap line you mentioned but after comparing the percentages was like nope. I also like sulfur for enhancing the funky aromas. The other side of the argument is that I always grow from seeds and pick four different varieties so I never really learn a specific plants needs. They sort of get what all the others get vs doing clones over and over and learning their exact requirements.
well you mentioned iron and the other micros. Tap has more than GH micro and DG FP so i'm not sure how you come up with that it lacks micros. what are the micro % of jacks321?
