Not getting good crops off my plants

i have a problem , plant is not producing enough yeild. only under ounce off a decent plant , any soloutions please.

Learn to grow.. Properly.

details on your style and setup would help.....

even if you were only running 150 watt Hps, you can yield 1g/watt of light if done correctly...

using optimum grow and optimum bloom and boos. 400watt light . grow lux soil bio biss plant feed . are they no good to get alot of bud? am only averging like under half an ounce off each plant

how close if your light,what temps and what humidity are you running?

what strain is the plant,now many times do you water,what soil are they in?

so many damn things to say,it could be anything

try a different strain?

veg longer and look into LST supercropping and top and FIMing

ha ha maybe a case of bad room syndrome, well i know u dont need very good air circulation 2 veg a lanky plant but i woulkd guuess its your air flow hook ur exhaust 2 the light and take the lens off so all of the air sucks up twords the plant, then make floor vents or some other type of inlet, if u dont wana cut hole in your floors by a co2 booster. i heard their good for 1 plant rooms

yes we could be here all day to correcct the problem lol. what about if i scrap that and put me on the right direction ?

i think if u put ur mind 2 it you will figure things out read up on facts or explain why ur garden sucks so bad lol
