failing plant

What could be the cause of a plant drooping and loosing color to a pale green from very dark green.It is afghan from seed grown in miracle grow time release fert in 10 x 10 pots for 7 weeks under 1000 hps and are 25" high and 12- 16 inches girth.Have been just watering and misting ocassionally with liguid seaweed.I did have one of these plants having nute burn and lost 3/4 of it's leaves and eventually came back but with lighter leave color as this one is now.Any help is appreciated ps I'll add a pic or two later on this evening Thanks again all

looks like too much water

thanks anyone else want to try

Has the temp changed? How much water are you giving them? It could be that time release stuff, starting to burn.

temp hasn't changed ,watering to little if anything and the soil isn't MG.But it does seem to be either nute burn or ph lockout.I don't think the roots will bring up any water because she is dry.

If ti is really dry, water enough to soak soil (it will run right through if really dry), then give some more a little later. After that, don't let it dry right out, and don't over water. Watch the soil. It will start to pull away from the side a bit and will be lighter in colour. The leaves will be lighter as well. Water then. You risk stress on your plants when under and over watered. As for the nutes, not sure with time release stuff. I would try to get it out if you can or add some plain soil mix to it.

Um, not sure if i'm right but I'm using a 600w HPS bulb and it gets as hot as a cunt. A 1000w HPS would probably kick out a fuck load of heat, mine turned a light green under the intense heat so I started to rotate them.

I got 3 fans on them and slowly growing under them they are now 24" away from the 1000hps and seem to love it.Someone said that maybe since their growing under optimal conditions they can deplete the fert in the time release soil quiker then what they say in the directions for fertilizing.they have grown to 2' in 7 weeks and fairly full.
