So I am growing super lemon haze in 20 gallon pots. The medium is 50% ocean forest soil, 50% and Pro Mix. I have 4 x 600W lights 2 MH and 2 HPS (I just put them into flowering, I am going to switch over to all HPS soon). I have had this problem recently with leaf curl. I am not sure if I had the lights too close (I moved them up) or if I just wasnt watering regularly enough. I have attached some pics, any help greatly appreciated. Peace and Love!
Downward leaf curl, help PLEASE!

Yea man thats heat stress from the lights.
Edit: The hps will run cooler, so you can probably drop them back down after you make the switch.

I agree it looks like heat stress but the lower extremities of the plant has some serouis browning going on.
I see, don't know where your seeing the browning, there really isn't any on the plants - may be the lighting or camera. But the leaves are definitely curling bad. This is occurring only on the tallest tops on some of the plants. I am thinking it may be because of heat from the light too, seems like the tops of the plants are losing water faster than they can suck it up.
Sure tale sign.

hazes/sativas dont like too much NPK at once...
my hazes do that pretty bad when nutes are high

it has nothing to do with the lights or heat.. heat stress curls the leaf edges upward like a canoe.
Clawing is from excess nitrogen mostly, but overall nutes are probably too high.
your ph may be outta whack, making an imbalance of available nutes at the root zone.
flush em out really well, lower nute concentration, and check ph.

I've been having a similar problem, although not quite as bad as I've been managing it with less light, and using fresh air instead of enriching with CO2...
It's slowly progressed over the last 2 years for me, and now looks something like what you have, though like I said, not quite as bad. I notice you have digital ballasts which have mad RF interference. I can't even use a rez ph meter because of all the interference, only a pen meter will work around my digital ballasts.
Anyways, I've tried just about everything over 2 years of multiple grow rooms testing to figure out the problem, and in my mind all I have left to test is getting rid of all my digital ballasts due to the possibility of mass RF exposure hurting the plants, or just scrapping the strain I've been working with for years now, which I really really don't want to do. Maybe my strain has a virus, I dunno....but I;ve been given a couple cuts from other people, and they all freak out when they go into any of my rooms, or any of the rooms my friends have modelled after me.
I've tried tons of different temp and humidity combos, tons of nute combos, mostly with GH but also tried supernatural...nothing seems to do the job....
Anyone else have weird problems using large amounts of digital ballasts?

Growing the same and had the same problem and it was not from heat. Pretty sure it was a nitrogen excess problem. Flushed soil with ph 6.8 and cut back on nutes, looking real nice now.
