Low yields, need some help.

[Medicatetoday]

So i have a 400w Hps for flowering and i flower at least 5 plants in this light with a 3x3x5 growroom.
My yield per plant is just 15 grams, i had one Bubblelicious from Nirvana Seeds with 30gr dry in the final but thats it.
I just want to learn how to get 2 ounces per plant or something like that...
If you can help me i appreciate that! :)

Need a little more info to help ya man. 1st timer? Experienced? Dirt r Hydro? How long did you veg them? What nutrients did you use, if any? Help us help ya!

5 ft. in height is not helping, anything....6/8 ft. would be better for big plants. IMO

Im in my 3rd grow.
I veg for about 1 and a half month,i top every girl to achieve more tops,my temps are 82F,i use All Mix soil by biobizz, with organic nutrients like Bio Bloom, Bio Grow,Top Max,Bio Heaven...
I put my plants in flower when they have 12 inches-15 inches.
I got a fan circulating the air inside the growroom and a 107 m3/h intake and outake 190 m3/h.
400w hps with an adjust a wings reflector.

Just from the info you gave, you need to veg longer and top more trim bottom branches off or SROG. Because of the 5 foot high room you need bushmaster bad. It keeps them from gaining height and so they bush out and go straight to maturity. Maybe get your temp down just a bit.

Doing very well you should get .5 grams per watt. 200 grams. more than that is excellence.
Patients in the veg time will pay off. I started very similar to you and went to hydro to find my way to what I needed. I do very well now and am finding my way to excelence.

I would also advise adding some CO2 to your setup with the temps and you may have good effects

That sounds like a great set-up. I've used Biobizz before, good results.

15 gm a plant is not good. I've done a lot of grows with 400 watt. Over 400 grams is normal. Average number of plants = nine. So an average of 50 gm/plant. I use 3 gallon plastic grow bags with rich organic medium, home mixed. pH of well water 7.2-7.9. Water is drawn into a 5 gallon tote (at this time of year the temp is low 50ºs), Correct pH to 6.2-6.5. Run airstones for 24 hours. Temp goes up to 65º - 68º. Check pH, water the plants.
I do veg for eight weeks or even more. But with 5' height six weeks sounds good for you. I crop at the third and six nodes. Like when they are tiny. I trim all the lower growth but I don't worry about height. LST would word great for you too.

You need genetics, that match you and you style.

I suspect you're adjusting your pH to low. Can you explain what you mean by "rich organic medium?"
