Three weeks in and my plants are drooping!!

I have had some yellow spots and lost a couple of leaves due to over watering, got over that, but now some of the leaves are curling up at the sides.

Has anyone got any ideas.

They seem healthy otherwise and seem to be vegging quite well (for as much as I know at this stage).

The ph is 6 and the temperature is spot on. Any help would be greatly appreciated

"spot" on what temp? and where are you measuring?

the temp is 25 degrees C and i am measuring right next to the plants so I get the temp where the plant is. Is that correct?

To be more informative, i have two nft trays with 8 ladies each in them, they each have a 600 watt light on them. The temperature guage is in between the trays because i thought that i would get a more accurate reading there.

To be honest, I know **ck all about all of this, but i aim to be the best i can be at it.

80F is what i shoot for. got pics?

i am at 29 degrees at the moment, which is 84 degrees. just taken a picture of my two 'droopy ladies'

how long has it been since you watered since you said you cured the over watering problem are you now underwatering cause folding leave like that often is what plants do to hold in moisture. whats your humidity like and you should get a mister to be able to spray your leaves to keep them nice and wet plus plants can also feed through their leaves

humidity is too low, temps are too high. Take a picture of the soil and let me get a better overall understanding of your situation...

Def looks like heat and watering problem

i agree with grnmn, id say get some fresh cool air into your grow room and get the humidity up a bit, how far have you got the plants from the lights? are you venting out the warm air?

The plants are about 3 feet away from the lights (two 600W)

To be honest the venting isn't what it should be. I set up an old caravan in January when it was minus 2 outside, so I was more concerned with insulation. I have got a fan on the flowers to keep a decent airflow going. I have been out and put some open buckets of water around the grow area. What humidity should I be aiming for? (Its 26% at the minute)

humidity is up to 32% now. is this closer to the mark?
