First Grow! 600watt hps, 'Big Bud'

Hey ppl this is my first grow and it seems to be going well.
Have 5 BB plants all 42 days old today (exept one which is 10days younger). They havn't shown sex yet so I decided to induce flowering yesterday for about 2-3 weeks to find out what sex they are then ill switch back to veg because I wanna take many clones and as i only have one grow area i would like for the clones to have some time to veg before i put them into flowering. i know i could have used the paper-bag method but id just rather do it this way.

using:

-Miracle Grow nutes (only started feeding last week at every 4th watering)
-soil which has low nurients for about 6weeks (forgot the name lol)
- 600watt hps light.
-oscillating fan which is on 24/7
-humidifier which is on 24/7
-heater, keeping temps between 22-26 celsius during day and 19-22 celsius during night.

I was using a crappy 60watt fluro for the first 2 weeks but i saw that it was incredibly shit lol so i sprung for this new light which is working amazingly....

unfortunately i only have pics of my plants at their current age coz i deleted the pics of when they were younger for some reason lol... enjoy and please leave comments

nobody go anything to say????

i think that one of the plants may be startin to show sex ill get some pics up ina while and you can all tell me what you think

They look nice and healthy - good luck!

So iv been reading up on fimming and topping and decided to give it a go... i fimmed 4 plants and topped the 5th one.. hope i did it properly here are some pics
