0.17 g/w consistently

I'm going to go ahead and say you're wrong. B vitamin deficiency isn't going to set you back that bad. You're doing something wrong. Please answer our questions so we can help further. What is your ppm and ph run off? If you aren't checking this.. Your not growing, your guessing.

4.5 pounds per light?

No one said 4.5 . But 3 per light is definitely achievable now a days with the right genetics and room.

Ph - not following. AN has PH Perfect and the few times I've measured it has been just that - 5.9-6.3, or perfect.
Ppm - not following. I add 4ml/l of Grow-Micro-Bloom and 2ml/l of B-52 into the reservoir. Again, the few times I've measured I've had a net EC of 1.4-1.5.

Light? Temps? Veg time?

Agreed, don't listen to these noobs, they haven't mastered growing yet and don't understand plants needs vitamins too. Definitely sounds like a Vitamin B deficiency, that would definitely explain 0.17gpw. Red Bull contains B6 and B12 which can be used as a quick fix, and the sugar in it helps nutrient uptake and the taurine keeps the bennies active.

I hope this helps, good luck!

I am absolutely amazed at your ability to diagnose a problem with minimal information and no photos...and to do so with such humble grace
I bow in the presence of your greatness

What a poor and misplaced attempt at sarcasm... scroll up for a better example...

If you are giving your plants a full three part fertilizer then they are most likely not vitamin B deficient, at least I've never had that issue but I've also never ran AN. Since you have given almost no information, I'll guess.

If you're in hydro, I'm guessing the water is either too hot or too cold, I'll guess the water is too cold since it's winter. Also if you're in hydro you should have a ppm/ec meter and a ph meter/test kit and use them regularly.

Do you have your light on a timer and not interrupting the night cycle at all?

Were the plants even fully matured?

If air temp is 70-80 degrees, water temps 65-68 degrees, nutrient level is in a good area not too high not too low, you strain is not a tiny yielder, you got good air flow, let plants veg out long enough/or run enough clones to account for lack of veg and you never interrupt the dark cycle. Then I'd say you got some serious bad luck and I would change strains or quit. Not suggesting to give up on growing, but it's not for everyone. I've had several friends see what I do and think it would be a fun idea and they give up relatively quickly. Good luck.

Well there is your problem, you had a sheep moment and did what the bottle told you to do. I never go over half strength with advanced nutrients. I would be very surprised if that was your ec at 4ml per liter. get yourself a good ph and ppm meter and check again. Do not do what the bottle says, your plants are probably locked out because you used too much nutrients . Checking once in awhile is what you do when growing in soil, not hydro.

Is this dude serious with the redbull thing? Do not give your plants redbull lol . Fucking trollitup

If you're getting 0.17g/w, you need to learn canopy management techniques.

That means ending up with a full even canopy in one way or another. You will yield very if your flowering plants do not take up the entire canopy area.

It's not a complete failure, just a pretty bad job. 0 is a complete failure, and that seems to be pretty common.. lol

spandy said:

.17 gpw is not "mastered", what it is, is .17 gpw away from complete failure.

Also, there's no such thing as Vitamin B deficiency. Plants produce all their own vitamins...

Fools... (I know sativied was joking, but the rest who even humored the chance that it could be a missing vitamin are fools!)

Exactly.

Plants don't eat vitamins, they create them. Not getting that is imHo not fully appreciating plants and fruits... And before someone mentions AN and vitamin research, that's for during tissue culture when the plant-to-be isn't able to produce all the and enough vitamins yet. But even if plants somehow benefit from adding vitamin B to the medium, it's obviously, definitely in no freaking way, a cause for such low yields. That's not just claiming it's beneficial but implies essentially that vitamin B is an "essential element"... absurd, like giving red bull.

I'm doing a very sloppy run on organics with improper feeding, watering, temps, and I may even have to harvest a few plants earlier than optimal, and still, I'd be surprised if it ends up being less than 0.5gpw. If you get less than 0.5gpw it's probably because like churchaze already said, you're likely not using the available space efficiently on top of probably a few classics like over-fertilizing. OP said he uses a small canfan which doesn't sound good either. Should be at the very least 250cfm / 400m3h for that setup (a 400watt space with 600watt bulb...), more if a carbon filter is used.
