Please help - plants in trouble

Hi all. Indoor autoflower grow under CFLs. I usually turn 8 plants around every 2.5 months without problem.

The only thing different with this grow is that the grow room has obviously been a lot hotter because of UK heat wave. I've compensated with more water. Have a good oscillating fan.

Am halfway into the grow, and some of the plants appear to be really suffering. Many of the top leaves are shrivelled, edges look burned/brown.

Is there any way I can rescue?

Any help gratefully received.

a good misting with some ph'd water would help, maybe once a day, to increase the humidity.

Just make sure you turn your lights off when misting

Got pics of your plants? It could help diagnose your plant problems.

Are you a soil grower? Over-watering, I've read, can lead to slow-release nutes in the soil being 'activated' too soon, and in too high a quantity. As per the advice above, misting the foliage with pH'd water during lights-off would help keep the plants hydrated.

Thanks everyone for the suggestions. Will try and get some pics up later.

Over-watering could be a possibility...

PH is good. I think it's heat stress + over-watering.

I've moved lights up, and will turn lights off for 6 hours each day (as they're autos, I've had them on 24/7).

Will also water considerably less.

Any other suggestions? What's the normal solution for plants that have suffered from over-watering?

Thanks everyone.

Halfway into indoor autofl grow - two of my 11 plants are really suffering with shrivelled, browning leaves. PH is fine, so I think it's heat stress + over-watering.

Can I save them?

What are the solutions?

Thanks so much. (sad me.)

when you turn your lights out spray them with water and raise your lights if there sitting on them they should be about 2 inches away if your using cfls,

Spray water with the lights out? Cmon man that's just B.S. Why would you want to in the first place? Moisture and water at night will cause you nothing but problems...fungus for one. Pic would be nice to get a better idea of whats going on. Crisp leaves doesn't always mean bad things, if your not pruning in a cramped room you will have issues like this. More info and pics please.

Pics tomorrow. Flatmate out with my camera.

PH fine. So it could be one of three things or a combination of all three: nute burn, heat stress or overwatering.

So - question - would there be any point in transplanting?
