Is my set up killing my plants?

Not had a chance to do too much, opened all my tents flaps/holes, just turned my extraction to max and it's now reading 93f?!? I'm aiming I go out tomorrow to my local grow shop for some advice but I'm gutted it's going so badly.......

My friend has a 600w bulb, no extraction, only an oscillating fan and only uses cheap soil and tap water - he always gets good, regular crops - am I doing something else wrong or is it just the heat??

Ok, disconnected my filter ducting and stretched it to just above my light, added a more powerfull desk fan, put some ducting in one of the holes just going out into the room and I've got the temp from between 84f - 86f - happy days - hopefully it'll stay there....

Id do a smiley but can't get them to work......

I know I need pics and will get some tonight but....... I've got 4 sensi seed super skunk autos that are about 2 weeks in, they seem small and the lower leaves started to go bright yellow but now new leaves are yellowing too..... Now, I presumed that was because I over nuted them far too early and took it as read that it was my fault... I've also got three critical rapido (barneys) that are a bit younger (about 9-10 days old) that have only ever had water, no nutes at all, and these are now showing signs of yellowing at the end of their leaves.

My tents 100 x 100 x 200, I've got a 400w light, extraction fan and an oscillating fan - my extraction fan sucks my tents sides in loads, could I not have enough air in my tent??

get some bamboo cane poles and use them to stop the sides of your tent from being sucked in.just add them to the frame of your tent so you have it like this on the back and sides.

the middle lines are the bamboo canes.so basically what youre doing is filling in the holes in the frame (which allows your tent to be sucked in) with bamboo cane poles.you dont need to take your tent apart,its very simple to do and you should be able to get bamboo cane poles already 100 cm long.you just need about 20 altogether.

If there's a passive intake at the bottom (maybe 2?) and a fan extracted output that leads out a window and your just feeding water, using a 400 and watering every two days for those little plants, I'd say there's a possibility of an over water issue.

-get a fan for moving the air in the tent
-check your soil run off pH
-check the pH of the water your using
-raise your light to 25 inches to give the little guys a rest temporarily

Soil should be sand dry for the first 1/2 inch to an inch of soil and only slightly moist past that before you water again.

Apart from a bit of additional grow space what else is the benefit of doing that? Great idea though, for additional space.

Thanks for all the help/replies everyone....

Despite all that still got the same issue, temps now between 83f-89f, the four I over nuted are doing nothing and the three that have just had water are showing the same signs as the rest, I feel like giving up already........
