We don't know the age, stage, or anything else about your plants. Pics would be helpful. You're probably either overwatering or you need Ca/Mg. Show us first, though.
 
Can you post a whole plant photo with only a daylight fluorescent light and also give us all the details of your grow?
Are you growing in soil? Do you let your planters get paper light before watering again? What is your temperature with the lights on? What is your temperature with the lights off? What is your humidity running lights on/off? What type of nutrients and how much? Have you given them anything else?, list it all! What is the strain? What type of lights and how far away?

List anything else you can think of and I bet we can help. If you don't thoroughly list everything with a picture then it isn't likely you will get a great answer.

sorry . i didnt upload fotos i forgot.

i just added those ..

18 days old, veg stage.

few days ago these were underwatered . so i watered to all plants

with 1/3 strength of nute with ph 6.0~6.3
 
It LOOKS like legitimate Phosphorous and Nitrogen def. The soil even looks like you give it time to dry. How often do you water? You should raise your pH .1 or .2, though. You are in soil.
 
I dunno, let's see what other people think first, but try 2/3 if they concur, since you already gave it 1/3. And raise that pH a little.
 
You can't use your finger to check if your soil is dry enough with that large container you are growing in it is to large. So I think your soil is remaining wet a lot which that alone can lead to root rot. I am betting on top of that you are running to high of temperature. I need to know that is not true before I am willing to help you further. So what are your temps lights on and lights off? What is your humidity lights on and lights off? <=== important also

what type of soil mix?

what the hell are you growing in?


do you have lights?

i have a 1000w LED(i only use veg mode output 450~500w) + 400w MH(i only use this at night for 4 hrs) with full ventilation system.

humidity is around 45, leaf surface's temp is 25~26 C around 80F always using fox farm . (air temp is around 23~4C, 75~78F)

i am growing [3 Ice , 3 ak49 , 2 wonder woman ]

p.s) ive never watered after i transplanted yet(3 days ago)

could u give me some advise?

4 hours is way unacceptable. You won't yield well, and you should veg them, which usually requires a light schej above 12/12.
 
Yes let the container dry out all the way and test it by picking it up. Night time temps need to be at least minus 10 degrees from your lights on temps at the planter level because I want the planter to remain at 68F to keep root rot away now that you over watered. People think that root rot is the end of life for a plant but honestly it can't even keep up with marijuana if you keep a low night time temp and you are allowing the planter to dry out completely. You know those plants that grow in the cracks on the sidewalk? Marijuana is that tough but it needs a little help from you.

Your plants are hungry like Olive mentioned and actually I think that is caused by a problem in the root zone although 1/3 nutrients might have been a little light. I can't advise you to feed them stronger without knowing what nutrients? I might suggest that you use a wetting agent and foliage feed them which usually I don't recommend a wetting agent but your leafs are in trouble. A wetting agent allows the nutrients to stick to and be absorbed by the leaf.

Actually I am worried to give you advise because I am not used to dealing with a plant that is in this bad of shape, this much dirt and also pushing temps to the maximum also. The best advice I can think of is lower the temperature, roll the lights back some, lightly foliage feed them with a wetting agent such as wet betty and let her recover. I don't think 1400 total watts is needed for that plant when it is full grown let alone 1000/2=500 watts for 12 hours then an additional 400 more watts for 4 more hours?? I think a 23w 6500k daylight cfl bulb would be perfect and especially helpful with the recover. (I mean turn off that 1400 watts and replace it with 23 total watts of bulb)

I CAN'T UNDERSTAND YOUR LIGHTS HOURS! I guess you are saying 500w HPS of light for ????? many hours then you're adding an additional 400w of MH for 4 more hours? The smallest footprint of a 1000 watt HPS lamp is 3 feet by 3 feet and that is wasteful you should be building a 4x4 plant for that 1000 watt lamp. I dunno, I am really disorganized now because you are giving me bits and pieces of info and I am an old stoner bro.

edit: couple edits
 
He's saying he's using both the veg strength of his 1kW LED (near half) plus his 400w HID in tandem for only 4 hours. That's craziness. Not trying to put him down, though.
