Mass Cull: I'm wasting my time with these.

Well.

Things have gone from bad to worse. This grow has been plaged with trouble since day one.
All the plants are a pale green, Suffering from Heat stress (The main course of all this I think). mainy have shriveled and dryed leaves.
Im pretty gutted. Esspacly as my first grow went so well.
Even the Cuttings are looking unhappy.


I Have two opptions.
One or two plants are looking savable.

I can, try and revert them back to veg and keep them going until the end of the summer, and then take cuttings off them.

Or

I can, Change the 600W light for a 400W light and hope that helps lower the temps enough to a workable level. Keep a best plants and see what cuttings I get.


Questions.

I have just finished week one of flowering and i'm wondering what will happen if I take some of the stretch plants and chop there heads off? will the bottom half the the plant bush up and grow buds?




Photos.
Have a look at the plants, they look a little extra yellow beacuse of the light but you get the idea.

I always take my cuttings this way, it has always been compleatly fall proof. I'm baffeled as to why they aren't doing well this time.

If it is too hot the plants will suffer. The big ones will be pissed and so will the clones. Find a way to lower the temperature in the room.

get a small portibale ac unit and put in it or some thing like that cuse youre giving them a heat stroke

Quite.

The clones are in a diffent room to the big plants, they where taken before the big plants got ill and are under a 125W CFL. Temps and condtions in there are perfect, I'm baffeld as to why some of them are looking so ill.

But any way I think I may have had a break through, So I'm holding off killing them for a few more days.
I think I may have been hit with multible problems at the same time.

I have built a self watering system, the plants are in perlight, I had it set up for 3 short waterings a day. At first I thought I was over wattering, so I dropped a watering cycle to see what would happen. The next day all the plants where wilted and unhappy.
But now I bealive that, That night temps climed very high, coursing the plants to burn and use an exses of water.

I have temps been able to keep temps just under 30c and I cut the watering cycles to once when the lights come on. The plants are looking better this morning, only a little and maybe it's wishfull thinking but deffinatly think there might be an improvment.
