32 degrees in the room seems a bit hot. I see what looks like mild heat stress on those leaves. I don't know for sure. Wait for others to reply. You'll get your answer.

Yo Ho Ho N,

Well first things first,

Welcome to the site bigbud100506. We certainly do hope that you will enjoy yourself here, and maybe find what you are looking for in the way of asking , or teaching others as well. Do remember to look over the site rules, they are few, and easy to abide with.

Hey guys. that temp of 32*degrees celsius converts to approx. 89.6 degrees Fahrenheit, That my friends is way too hot. You are certainly stressing them babies.

MJ seems to grow at an ideal of 76*-78* degrees Fahrenheit, or you might say 25.5* degrees celsius.

Hope that this helps

smoke in peace

Welcome to MP...temps are a bit on the high side...you also might want to veg a lil longer...unless they grow quite a bit in the next week they seem on the small side...are you limited on your grow space? If so you might want to look into training them...

What dimensions on grow space?
That 600 will crank out heat-You may need more ventilation.

ok thanks guys my grow space is 1.2 by 1.2 buy 2 metre high i may try a diffrent light like a 400 watt or cool the 600 watt with a fan i dont want to mess with bending tech yet untill i can master the plant which is chronic. i know i might struggle for space i have been told but i think it may be ok we will see. thanks for all the advice i will cool the temps down and update as soon as poss i will be checking them in a few hours so i will let you know then as last night i opened two air vents to let the heat out. i will veg for longer if i have to but before the curling started they was growing extremly fast over night changing every day. thanks for the info guys.

 

[GeezerBudd]

You will definitely need constant ventilation.
You could try venting through the 600 then blowing it out.
Have your intake down low.
I guess we'll see.
