New Member wanting some input please

Hello I have done about 3 grows, all done indoors, first in a 10X10 room secluded in a michigan basement, I have to recover pictures and will post them tomm. From there I moved and constructed a bigger room. 15X15 in Colorado and then recently started another project in pac mid west (cali). My first was with basic fox farm, 4weeks v 8 weeks F (started from seedlings), these grew good, (considering my first attempt I was pleased with the results about 23-26 grams average???).... My second one I releized bigger room is better for the amount I wanted todo, so I just space it out more and did the same as the first time.( this time they were able to grow and breathe more, got about 25-30 grams average this time).. Well now I do not have access to a nice basement and have built a room in a garage in mid west california and used home and garden nutes with austrailia( increased the cost in nutries by like 10X and I wasn't as happy with the yield as each plant only produced about 12-17 per plant, but the quality was much more improved) so my question is before I start another one why did the better nutrients produce less buds?? Was it because of the climate? even tho the room was controlled the same temp and humidity. Never used co2. What are your suggestions to get my yield up to about 2 oz's per plant in a 90-120 cycle (beginning to end)?? I am thinking of reducing the number of plants so that I can divide the garage into 2 sections, one for v and one for f. (approximately both rooms 13X13 or 12X12) so that every 6-8 weeks there will be one ready. I am using 1,000watt lights 210digital balace, what would be recommended for the 13X13 room and how many growing ones should I limit myself to in there? All advice is greatly appreciated, pictures would be very helpful as well. thanks!!!!!

Have you had any pest problems?

No I haven't had any noticable problems, I do however have these little fruit fly like things.. However I don't think they are causing any damage.. Thanks

Those "fruit fly's" are likely fungus gnats. Although your correct that the fly's themselves don't do any damage. The maggot babies suckling your roots will!

Where they all the same strain?
