What is my major malfunction?? PICS

ok guys these baby girls are about 2-2.5' tall and are placed into 5 gallon buckets. lots of holes so good drainage. this is day 5 of 12/12 and the top leaves and new growth seems spindly and weak. it is yellowing somewhat but I have heard that is normal for light shock in the first week of flowering. I use ph balanced water and nutes and check it every time. I haven't begun flowering nutes yet I was told to wait for a week of flowering and will be watering with big bloom in a couple days. can you guys give me some insight on what may be wrong?
FYI I have been having som trouble with the heat in this closet during night hours I am geeting a small portable a/c today to geep the temps right during night and day hours. I have a dehumidifier in there and keep it pretty consistant 60% during day and 50-55% during night... Could it be heat stress???
thanks all and happy growing!!

Just my unprofessional opinion ... I think too hot, and not humid enough.

i think you are probably right!! arrgghh if it isn't one thing it'd definantly another with these girls!!

how close is the light to the top of your plants?

about 5 inches

That's plenty of humidity; my plants are in 35-40% humidity without that problem, of course I am also giving them silica.

But I want to know if you are feeding with micronutrients too, if you have a complete fert?

Zinc def/lockout can cause crinkly weird-looking new growth.

It's hard to tell from those pics and your description may need your npk and light source included.I have seen plants do this when not getting enough light....Like 20 watts per sq foot at that stage(30 being the min).You said your lights were at 5 inches so I might assume you're using flourescents which can cause this lightening of leaf color.You might have too low a ppm of nitrogen but only you'd know.Perhaps a little more info and we can help.

i use fox farm big grow and tiger bloom for flowering. thay have just completed the first week of flowering and the plants have been showing these signs for about 5 days. I will be giving them the first dose of flowering nutes next watering I use cfl's and and 200 w hps but ordered just a 600 for these plants and they should be here this week. I think they are getting plenty of light, the leaves are really thin and wrinkly which makes me think it is too hot. the humidity must play a part in there somewhere but I don't know if it's too much or too little....lights on it is 60% during night it is about 50-55% anyone else help? they are still looking bad. coloring is coming back a bit... could this be light shock from the change in light regime for flowering??

im no expert but they look to dry try spaying them with pure water from an atomizer [water sprayer ] before the lights go off so as not to scorch

actually its better to spray righ tbefor the lights come on so that the excess water will burn off. i spray mine 2 x a day when not in flower for foliar feeding.

imho get abetter fan and be done with it

Yup.
If your huimidity is over 50% and they are showing that, and I know FoxFarms has micronutes in it, your temps are just too high.

yeah you guys were right I had to buy a portable A/C to add to the expensive assed dehumidifier... I keep the temp at about89 during daylight time and about 72 during lights out.... after a few days they came back with a vengence you can see the updated pics that I posted today here

can you spray the plants with water during flowering times...I am beginning week two of flower

With an a/c you may not need the dehumidifier.
And if you are running a dehumidifier, then why do you still want to mist your plants?
It makes no sense.

I don't want to mist my plants... I just read in a reply above that someone said they mist when not in flower stage and I was wondering if it was bad to mist in flower stage because before I put the a/c in I sprayed a couple times to try and cool the plants off... That's all

Oh-
I wouldn't mist after week 2 or 3 of flower for risk of mold.
You should be fine now.

thanks... they are budding like crazy!!! I have to use an a/c and dehumidifier because if I don't use the dehumidifier my humidity level reaches 85-90% It is real hot and humid where I live.... I am keeping it at bay though.. my plants love the 400hps!!!
