1st grow - need good opinions pix included

First i'd like to thank rollitup.org for such a helpful site.

I am a nubie grower.

• I have a closet grow with three babies inside. i only toppeed them once so there bushy and branchy. Sorry unknown strains I wish i known.
• Running on a 400watt HPS light im at week 10 on flowering and its looking good but not better than most people here . Ive been looking around this forum for a long time. Read interesting stuff learning new things day by day i look on here. Its not helping me quite well just looking around so ima have peoples opinions on my grow.
• I'm running on foxfarm nutes. the big bloom ,tiger bloom. my feeding scheduel is twice a week and 2 tsp per gal. and im using my bathroom sink water. I'm pretty sure the Ph on my water is high so when i put nutes in water i use PH down. my PH level in the soil is always around 7.5-6... i change my hps every 2 grow seasons. and i do have a 400watt ballast.
• i water about a gal for each of my babies. i have no ventalation just my window is just open and its about 20 degrees out every night so the temp inside my room is about 70 and the temp inside my grow closet is like 75. i dont think i need better ventalation but i got one fan just blowing around inside the closet.

I need more advice and what can do to have more when i harvest.. how can i make my buds more dank and tasty :]

I dont know anyone else that grows around me so I dont really know to expect ... the right from wrong? or...

should i top it more?

I dont have much room to grow so whats the maximum yield i can get out of one closet.
Im thinking about have like 8 plants and autoflowering wihtout vegatation... is that a good idea? they'll all be like 1 meter each so .. that a bettter idea to get more yield? running with one 400watt hps light...
im doing everything right i think and 2 of my strains doesnt have trichomes like one of them.. making me mad.

The buds shown look pretty good man need more pics but it looks like ur off to a good first harvest. The one plant that isnt producing thr tricoms as much as the others could just be the strain. Post some more pics, plants as a whole and ur grow space. Ive heard molassas can boost ur weight and taste when used the last few weeks b4 the flush havnt tried it yet but lots of ppl swear by it.
