My first grow

Hi guys.
Its my first time growing and my first time posting a question here.

How good do you think my girl looks for the 22 day of flowering?
Im using a 250w HPS.
White diesel.

Also i am having trouble controling the temp lower than 30c and humidity always around 50-60.
Can it be a major problem?

Looks good 30c is ok its kinda on the border but still ok when the temps are high cannabis uses a lil more potassium than usual so keep that in mind your humidity is great and is 22 days from first sigh of flower or 22 days from turning lights to 12/12?

Its 22 days after switching to 12/12.
By the way, my first week of 12/12 was while using a CFL then only i switched to HPS.
Should i count that whole week? or should i make the flowering period a little longer?

It takes about a week after you change the lights to 12/12 for the plant to start to flower so you would be closer to 15 days alot of people dont take that into consideration and just cut them down at day 60 and they tend to be a lil on the premature side

On my vendor of seeds site it says the flowering period is 50-65. does it mean from first sign of flowers or after switching to 12/12?

I just asked about that)
Thanks!

First sign of flower and your probably going to want to go to the 65 day mark you get all your weight,taste and smell in the last week or 2 so make sure you go full term

So i start to flush around the 58th day of flowering(after first flowers)?

Flush 2 weeks before you expect to harvest 48-55 and realy flush the with a coupe gallons of water per pot to rinse as much nutes out of your soil as you can and reed and rereed as much about curing as you can all of your hard work can be lost real qiuck with a bad cure

Im going for a trip for a week starting at the 07.09.15
Nobody will be able to take care of them.
Considering that situation what do you think is the best possible schedule of trimming them and start drying?
switched to 12/12 at the 05.07.15.
Can i leave them to dry alone?

If im getting the dates right it would be after you get back

Are they going to be able to go a week without water?

Well i guess no

what if i start drying them until the 06.07 so about 56 from first flowers.
Then dry them. do i need to take care of them while they are drying?

No but......you could be loosing a huge chunk of your weight i truley believe half of my weight stacks on in the last couple weeks and smell ,taste for how nice it looks gawd it would almost be a crime lol
