250w Indoor Organic Grow - Beginner

Hi everyone, I'm from Brazil, I'm growing for the first time and I thought that creating a grow journal could really help me solving my problems with my plants.
Well, first of all let me introduce my setup and all about my grow:

SETUP
-My grow is a metal cabinet that I adjusted. It's dimensions are 1mx0,5m and it's 1,8m tall.
-280 cubic meter/hour fan, that pulls the air from the 125mm cooltube, to outside the room.
-Phillips HPI Plus 250w for the veg and Phillips HPS 250w for the flowering
-Soil: 30%perlite, 30% coco fiber and 40% organic fertilized soil.

ABOUT THE PLANTS

-I have 4 little plants of an unknown strain.Buying Cannabis seeds is ilegal in Brazil, so I had to use seeds that came in the weed I bought here.

-They are about a months old and I had an underfert a feel weeks ago, now it is solved.

-They seem to be too small considering their ages. They are growing very slowly. One of the plants grew white a lot last week but the other 3 still very small.

-I always water the plants with water that have ph near to 6,5 and I fertilize them once a week

-I don't know if they are male or female yet

-The humidity inside the grow is around 75% and the temperature is around 77ºF

-I intend to use scrog when the plants are bigger

VEG NUTRIENTS (I didn't bought the flowering nutrients yet)
-Iguana Grow (Advanced Nutrients)
-B52
-RapidStart

QUESTIONS:
*What should I do to increase growing speed of the plants? Any other fert or something like that would help? I have to harvest them until the end of June!
*When am I suposed to chance the photoperiod of the plants in order to find out their genders?
*Wich ferts do you guys recomend to me to buy for the flowering?

like I said:
-Soil: 30%perlite, 30% coco fiber and 40% organic fertilized soil.

Because of the yellowing leaves I also thought I might be lacking in Nitrogen but I'm fertilizing them once a week with B52, RapidStart and Iguana Grow, do you think I should fertlize more often? This may be the cause of the slow growth of the plants right? Thanks!

Hmmm. Odd. Overwatering?

Humm I doubt that, I only water them when the soil is completely dry (it takes about 3 days to get dry). Overwater could slow down the growth like this? I don't believe that just this lack of Nitrogen could do it.

I was thinking and maybe it could really be overwatering, the past week I was travelling so I let the plants at the garden and rained a lot, let's see if now, with the plants back on the grow, the soil gets dry and they get better...

this pictures are from them a week ago, they started developing fast and are looking bigger now, but not as big as they should, considering their ages. I probably won't be able to harvest in june as I was intending to...

(after chancing the soil, the smaller plant got really dry and I thought it was dead. Now it started growing again and is alive, but still very small)

I've moved the plants to my smaller grow because I got some a bigger plant wich is flowering (420 Magazine ®)

My smaller grow has 2 65w fluors and has the dimensions of 1mx0,5m and is about 0,6m tall.
