Noob Unhappy with Flora Duo A+B in Coco what should I switch to? What about Canna?

[malufizzgig]

This is my first grow and I was gifted some GH Flora Duo A+B to get started but I can't seem to get satisfactory results in coco and my plants look sick and burned. I'm following their feeding schedule for part a+b. All I am using is the flora duo A+B, the rapid start during veg, and the calimagic. I use RO water, grow in coco in a tent under 1000w hps, and I keep my PH at 5.8

Plants are three weeks into flower. The leaves below the canopy in the tent are all turning yellow, some have intervienal chlorosis on the middle fan leaves, and one plant has weird brown spotting, drying and upward curling of the leaves on the newest growth near the buds. I guess I don't know enough about growing to make it work but it seems like these nutrients according to the GH feeding schedule without buying a bunch of extra shit is a bad fit for me. Just mixing the flora duo a+B and Calimagic creates a solution that's usually well over the PPM range they specify in the feeding schedule and always requires massive ammounts of pH up because the end solution is so acidic. The General Hyrdoponics nutrient schedule feels like it was designed to sell tons of bottles of expensive products at excessive ppm dosages and the product is mostly water.

I want to switch to something else. Please make some recommendations. I need something that is easy to mix, specifically for coco coir, isn't mostly water, and doesn't require ten bottles of snake oil to get all of the essentials that my plants need.

What about Canna A+B? Can I use that as just the a+b and Calmag or do i have to buy all the other nutrients in the line to avoid deficiencies?

Search the KISS method. Cheap and effective.

i started off on gh. and then went to botanicare, then advanced, then hum bolt, then h&g, et.c, etc. all i can say is most of these brands are going to require more than they're bases if u want a truly healthy crop..i personally don't mind mixing nutrients so i tend to rotate and sometimes mix match from the above mentioned.. but yeah,, gh is only good for a few of they're products imo.. i can say if u want something simple, you cannot go wrong with botanicares newer "kind" three part.. performs awesome and has calmag already in it.. u really don't need anything else with it and the results are nice… in my experience most of these lines produce healthy plants but the end results are always different.. my favorite synthetic to this day is still advanced, even with all the b.s they bring to the table.. i get the best flavors out of connie base with big bud, bud candy and overdrive.. don't need anything else if u don't want to spend the money… second favorite is h&g full line,, but its a lil trickier
takes longer to mix cuz u have to let the a\b set after mixing each,, etc.. if u want top notch smoke, try a.n. if u want total ease and still great smoke try that botanicare kind..
not saying theres not tons of good alternatives out there,, just my 2 cents.. hope i helped a lil,,, PEACE

I'm also curious about a line of vegan nutrients for cannabis, but I made another thread about it. The KISS method is really interesting, you just always use 7ml per gallon from seedling to finish + calmag or epsom salt? Nothing else?

i've really enjoyed using canna coco a+b the last few months. <50ppm RO, i add 1-3ml CalMag+ for most strains until wk5 bloom. i'm in straight canna coco or chowmix coco/hydroton.

really well balanced food, my plants like it more than the other lines i've ran.

i like nutrients that are the same for veg and bloom.

lines i've run before: GH Floranova, GH micro & bloom 6/9, PBP, and Heavy 16.

i think i'm gonna try Floranova Bloom again with CalMag+ it worked perfectly, it's just annoying how thick it is... requires insane shaking.

I'm using cns17 the coco blend. It's white. It sucks up nice in a 60ml syringe. It's a little thick but I shoot it thru my small aerator pump an it mixes it nice. The hydro blend that can be used for coco is like water an yellow or some other color. I throw in cal mag every 5 days or so. Also using liquid kool bloom.

i'm using flora nova bloom straight through from seedling to harvest.

 

[acridlab]

have heard kyle kushman is putting out a veganic nutrient line

 

[MiMedGuy]

Use dynagro. Learn your plants then fill in as needed. Your plants will love you.

The issue here is not the nutrients but the grower. No matter what brand nutrient you use you will not get the results you're after until you learn to grow.
GH duo is a very good line, just like the Flora series.
As you learn more about growing MJ you will come to realize that most any nutrient line works great, just look at all the diff brands folks are recommending to you...

 

[malufizzgig]

I am well aware of the fact that the issue at hand is absolutely my novice. I'm looking for guidance to help me or to find a nutrient solution that is a bit easier and seems more adapted for the specific growing medium I'm using so there's less to dial in and less frustration.

Here's the problem. I'm using the A+B and Calmag exactly as directed, feeding on Sun Wed Fri. My plants don't look completely healthy (much better than most first timers though) and I don't know what I'm doing wrong or how to remedy it. I'm feeding at a pH of exactly 5.8 with a regularly calibrated meter, measuring EC to the average of their recommendations. Do I need to be using the Floralicious, Liquid Koolbloom, and Rapidstart to get better results?

I don't like how their feeding schedule recommends to feed at a certain EC but when you mix the solution according to their chart, the resulting solution has a significantly higher EC from just the A+B and CalMag. It'd be even higher with the other products I don't have. To me this feels like they're making me add more to try and get me to use it faster, and I don't know enough about growing to know whether i should back off on one product or eliminate it or prepare the solution exactly as recommended and then dilute with RO water until I hit the correct EC for feeding. What would you do?

 

[stoned40yrs]

How many ml of A, B and Calmag are you feeding? First off hide that bottle of calmag as it causes all kinds if problems in coco when both your base nutes already have cal mag in them. Secondly at 3 weeks in flower you should drop the part A, way too much N going forward in your grow. Just use part B unless you end up switching nutes.

 

[mikeee420]

I think you might have better results if you feed every time you water. Also maybe try using a mix of half RO half tap or spring. Creates a bit of a calmag/pH buffer

Unless you're totally against your current nutes I'd recommend dialing in what you have already. That aside, if you really wanna switch I'd recommend the h3ad formula.. it's specifically for coco, so it should take away most of the guess work as you mentioned.

 

[malufizzgig]

I'm not totally against finishing up on what I've got. I'm just not sure if I need the other nutrients GH recommends for their simple drain to waste feeding that I linked to. Like, is my nutrient solution "incomplete" with just the A+B?

Just as an aside, my tap is over 400 ppm and I'm scared to use it at all. I have calmag though. And I can get epsom salt if I need it.

 

[malufizzgig]

And I already feed every time I water and I feed about a gallon of solution per three gallon pot Sun Wed Fri. Gives me plenty of runoff so I don't think buildup or lockout is my problem. My runoff is about the same as what I'm feeding, usually 5.6 or so.

try cutting ur tap with the r.o until its down to 50-90 ppm..

 

[stoned40yrs]

Quit adding that calmag. The Part A has too much N to use going forward at 3 weeks in flower. You need to subtract not add. You never run straight water thru coco until the final flush. How come you aren't feeding everyday with lower strength nutes?

right now, 2.5ml calimagic, 5ml part A, 7.5ml part B per gallon for a total of about 700ppm at 5.8 with RO. They're about three to four feet tall and packed in tight, so the lower leaves aren't getting much light. I wanted to learn how they grew naturally before trying techniques like supercropping LST and scrog and stuff so I could understand the process better.

I have six plants in a 4x4 tent. The very lowest leaves below the thick canopy are slowly starting to turn yellow and drop. Is that normal? They don't get much light. Everything that's getting a lot of light is green and lush. I have some chlorosis on the middle fan leaves, and one plant has some curling leaf tips and brown spots on the newest growth near the main cola. I can post pics tomorrow.

I haven't done that because nobody has told me to. Everything I read says something different about growing in coco so I decided to use the GH recommendations. Every time I ask online I get a ton of different answers and i'm never sure which is the right thing to do. It's really hard to be a novice and try to learn this way. How do I know which advice is sound? Which methods to use?

So are you saying I should just be using part B, nothing else, and feeding every day? How much per gallon? Why?

Doesn't the yellowing and chlorosis mean I'm not getting enough Nitrogen?

I haven't ever run straight water through them. I've fed with every watering since they reached the vegetative phase.
