Temps would be to high for my liking.
Do you have em in rockwool cubes in the system?
To me it looks like calcium or mag lockout, usually due to salt build up or ph flux in medium. i like to spray up until 3rd week of flowering in hydro with cal-mag supplement (1/4 teaspoon to a gallon of water for a spray) Also in rez but at a (5 to 10 ml per gallon).
Also what are temps in your room if to high also can create heat stress and take up more water than nutes. bringing me to my next question. how often are you topping off your rez? while water evaporates ec rise's because salt doesnt evaporate, i add r/o to my rez daily to keep topped up always. if i need to adjust ec i top with 1/4 strength nutes.
Hope this helps
ohh ya what is your huidity%?

If you can get pic right after lights out so we can see the leaves colors better. prob get quicker diagnosis.

are leaves falling off at all yet? if so it could be potassium deff. as well with red stems .
most of the time most fert dont have enuff cal,mag n iron and many other trace minerals that play huge role in uptake of nutrient and how plant uses nutes.

no rockwool in the system i transfer from cloner machines stright to areo ..
ok i will try to spray them .. they got better after i add cal mag .. but the leaves got back to green still dooping
the temp in room is 72 and water temp is 68
the humidly is 42 % night and 32 day .. any idea why leaves very doopy and claws look .. but it got greener which is better ... also i look in root the longer root i little tan and bunch of new roots coming out on the top .. i guess new root coming out mean it growing still .. it my first areo ever ! thank for your help ....

It could be a combination of too much nutes and the lights being too close. Those leaves won't ever recuperate. Flush and go very light on the nutes. Add some extra Micro for the extra nitrogen. Look at the new growth to see if you are on the right track. Then switch to Dyna Gro 2 part and use no magic potions or powders. That is a complete fertilizer and you and your plants will be happy. If you go by rumors and things that are just repeated on the internet you'll end up in deep do do again. Go by science, not advertising claims.

Keep an eye on your the PPM in the res. If you start with 0 ppm and have 600ppm the next day, then i would change it out so it's back to 0. Can take a couple days or even a week depending on your situation.

the bubbles breaking the top surface of water is whats creating oxygen. the colder the water the more oxygen is in the water, hence why in hydro best temp to have in rez is 68. i agree with warnerwh, mite be to much nutes. in the aero system do you have the water at lowest point in tubes that the plants are sitting in.

ur water is perfect. maybe to cold of air temp. plants arent using enuff water/nutes. too much nutes is bad when plant isnt taking it up. prob over the amount of nutes since plants dont grow as fast in 72 degrees compared to 78.
