need my plant diagnosed

Well here's my current situation: this is my first grow and I am growing the lowryder cross masterlow by mdanzig. I am using a 6 lamp 2 ft t5 fixture for lighting and I started the plants in 12 oz plastic cups and then 1 week from sprout I repotted them into 5 gallon grow bags with foxfarm ocean potting soil.

The plants realy took off when they got in the fox farm soil... After about a week I had some heat issues that caused some burning on the leaves but I moved the light up about another inch and added a fan and the the yellowing of the leaves stopped. The issue I am having now is that the plants look kind of droopy.

From what I've read this is normally due to being root bound or root rot, but a lowryder shouldn't need anything bigger than 5 gallons right? I don't think the issue is root rot either I've been watering when the bags start to feel light which has been about every 3 days.

The plants are currently in week 3 (closing in on 4) and I still can't see any signs of sex... shouldn't lowryder be showing sex by now? I see what I thought were the hairs that indicate a female but the closer I look I think they are just new shoots forming.

Anyway any help would be greatly appreciated.

Thanks

I don't see a problem here. It doesn't sound like you are overwatering, and a little droopiness is not a sign of imminent danger. They will droop a bit over night. As long as growth continues I wouldn't worry about it.

About your pot size: With flouros there is no need to go as big as 5gal (mind you it won't hurt) for a number of reasons, mainly because due to the flouros' lack of canopy penetration, you will not want to veg very long. Secondly, with Lowryder you can't veg very long anyway. Thirdly, you could use 1gal pots, fit more plants in the flower chamber, shorten the veg time, and get more weed. Also use less soil and nutes.

well, ARE YOU SURE they are lowryder/masterlow? lowryder flowers in about twenty days...
