Your 1000w light, if not a cool tube, should be no closer than 2' to your tops and even that is close with a 600w addition. Your leaves are dry and crispy..... hmmmm, I'm no scientist, but looks and sounds like heat stress to me... You are also poisoning your plants with magnesium and are over watering.

the reflectors are big kahunas sealed vented with 6 in fan pushing 425cfm and yes I agree after writing this up i started thinking heat stress... but where do you get overwater and mag poison?

It says to use calmag when your using Ro di water and the plants are dry when I water I only water maybe a quart a day per plant... should I not use cal mag when using ro di?

You only add it when signs of deficiency are present. By adding it everyday, you are introducing your plants to calcium and magnesium toxicity, which restricts your plant's ability to absorb and use other nutrients. Weed doesn't need daily watering. At most, once every 3-4 days, especially if growing indoors in soil.

I would leech the hell out of that soil and not feed the plants for at least a couple of watering. You should rarely need cal/mag, thats why I only have the small 8 oz bottle in my grow room. Your leaves will fold in half along the margins, as if they were clasping for prayer if you need Magnesium.

I agree that your over watering. Your not supposed to water everyday if you grow in soil. Take one plant out of its planter as if you were gonna transplant it. I but the is a layer of soil on the bottom of your pots that has the consistency of clay.

Next time add perlite to your soil so you dont have this problem. But just in case, i use grow bags so that I can manually squeeze the shit out of them if I accidentally overwater; Plus you can fluff the soil up by squeezing and manipulating the bag. Also if you use soil, your supposed to put a rock or sand or perlite layer at the bottom of the pot about an inch or so high depending on the size of the pot for drainage purposes.

This time, well, you have to trans plant them into better aerated soil. Or else stop watering them until they dry up as much as the can (itll never completely dry), or else take a screwdriver or some other long thin rigid tool, and stab and re aerate the soil until its fluffy again and thatll dry the bottom of the pots better. But of course, that'll fuck up the roots if your not careful.
(these are all drastic measures and not recommended under normal circumstances)

Then again, I could be wrong.
But you are over watering your plants

i just transplanted them last night into 5 gal containers and the bottom was solid dry root, no clay. there is perlite in ocean forest, there are drainage holes in the pot and yes when the plants were small i did not water every day. but now they are very large and can consume more then a quart a day i bet I am NOT over watering

I use hydroton at the bottom of my pots for two reasons, drainage and reverse waterings. the hydroton will wick water up to the soil quicker than pebbles or rocks. Sand is no good at the bottom of pots because it is going to just run out, same as perlite. Use river rock or hydroton. Hydroton is my preference for PH reasons.

I have been wanting to try the hydroton it looks like it would work well... Im sorry that I sound argumentive but Im very frusterated about this I do know a lil about growing and I know Im not overwatering.
the calmag thing im very worried about now, but not all the plants are doing it I guess different strains like dif things.. Im pretty sure the lights were way too close i have moved them up

I made the same mistake with CalMag for about 3 or 4 watering. I mistook CalMag burn for mag deficiency. I just flushed and havent used it since. BTW I was in veg when I flushed I dont know what the procedure is for a flowering plant.

Those pics show severe signs of Mg toxicity. Flush with reg ole water for a few days, and then re-evaluate your plants. you will not see a Mg burn turn back to a dark healthy green, but you will see the leaves flatten back out if you have fixed the problem. I know you probably arent over watering with temps that high, but those temps will inflame nute burn because you are losing a lot of water to evaporation, not respiration through the plants themselves. Stop using the cal mag for a while.. let the plant tell you what it needs rather than a label that is designed to sell you more bottles of the "magic formula"... good luck turning these girls around again. be patient, and you will see improvement.
