hey man, I always use unsulfered mollasses when my plants are in flower mabey the third week on. You should use bigger or wider pots for autos, I always use 11 litre pots. I dont use any nutrients for the first three-four weeks the soil has enough in there to keep em goin and you wont end up jacking your dirt up with salts and high ph and all that bullshit. I have a small cfl grow myself, a box 3 ft x 3 ft x 3 1/2 ft tall and use a bunch of 23 watt cfls on a light strip. If you want to cover your walls and go cheap use some dollar store car windshield sun reflector stuff, I used it for a while and did the job also try using one of those emergency blankets they work also. I just germinated two Auto purples yesterday and this is my 9th auto strain with 00 seeds auto cheese berry. Im on one of those quests for the best ( IMO ) auto strain and ya the quest goes on. Hope some of my little rant helps out. 1st post..
