Northern light auto day 40 looking ill HELP!

[WeedSmokerEire]

Started these 4 auto northern light from royal queen seeds on the 20th of july almost 40 days now but recently the new growth has been twisting and 3 of the plants havent got any visible buds yet though one has. Theyre in a 4 pot wilma using clay pebbles 600w hps and 2 airstones in res... Im pretty sure its heat related but im not 100% sure. This is my first auto/hydro grow so any help is much appreciated.

above: visible buds
Below: just twisted bud sites

Temps ?

Light height ?

They show signs of heat / light stress methinks

Also, do you have a fan blowing on them ?

 

[WeedSmokerEire]

Room temp usually sits between 27-32 degrees celsius
Res temps usually around 23 i start at 18 and it rises to around 24 by the time i change res again but i use cooler water when topping it up to keep res temp regulated as best as i can.
The light distance is around 1.5 ft from tallest top with a 4inch intake fan blowing between bulb and plants with a 5 or 6 inch exractor fan on the opposite side

Like so...

Sorry new to this ive posted some pics in the thread with some info for you

You don't have a fan blowing on the plant ?

Might want to look into that, and also raise your light a little bit

The fan isnt strong and not directly on the plants also the light is as high as it goes its only a 2m tall grow tent. I might switch my light cycle from 18/6 to 12/12 and keep lights on at night when its cool

If they are only at 40 days and you can't raise the light your going to need to do some serious training fast.

Also you need a fan blowing on the plant, otherwise you might learn about bud rot or mold a lot sooner than you should

Good Luck !

Your secret's safe with me big man! LOL have you ever seen autos at almost 6 weeks with still plenty of time left in them im starting to think 3 of my 5 seeds i got delivered are photoperiods as theyre just not like the other one which is packing on the buds already. 3 seem real slow is this normal?
