Put up pics, if you are using HPS lighting take a pic when them lights are off to stop yellowing of the picture.

Not familiar with that nutes but to me that figures sounds like and awful lot of nutes for a 3 week old plant, mines is 3 weeks old and i only just started feeding 0.5ml nutes (biobizz range).

You could be overwatering too. But until pics and more details are up no one will be able to help.

How much water are you giving them, and how often. What is the water PH. How much nutes per litre of water?

MORE DETAILS, THE MORE YOU TELL US THE MORE WE CAN HELP YOU, i mean we know nothing, Soil/hydro,lights,watering,nuts,schedule, cycle, i can go on and on but we all are here to help but we get frustrated when we come to help and there are so little details like your post, Im sure you did not mean to but please try from now on, I was guilty at first of doing it somewhat and learned if i just take the time to type the correct info when i asked a ? o would get my answer plus ALOT MORE....Will check back but could be anything from nitrogen deficiency to a PH problem...Good luck...

Watering twice a day is far too much, check about 2 inches down for slightly moist soil. If there is moisture and not dry powdery soil then it's not time to water. Plants that size do not use much water, water every 2-3 days. That's the time it usually takes to dry out properly.

You never mentioned PH, you should get a ph meter and monitor the ph closely if you are having problems. Also the leaves look like they are curling upwards, to me that means heat issues. I may be wrong though but that's what happens when I let my temps go a bit higher than they should be.

thx, I thought I might have been overwatering the smaller plants but I was scared id let them dry out but 2-3 days sounds about right.I have a 16 in fan in my tent but it still seems kinda warm in my tent. I check my PH just before i feed its around 5.8-6.0...oh ya about the heat my light intesity set at 100 should i lower it or just raise my light up a bit more?

a good measure in watering is the weight of the pot they are in. get to know it. Pick it up. you are obviously watering too much, but your plant looks plenty healthy to me.

Overwatering is WAY worse than under watering. Let your plant really dry out, check the weight of the pot and then water, and dont water till the pot is that light again, however long it takes.

That fan, its just a normal fan is it? You need extraction, something sucking air out of the grow area. Extract at the top and have an entry hole at the bottom for fresh air to enter. Just a fan blowing the plants wont work, thats just blowing hot air around.

PH sounds ok, see if you can catch some runoff from watering sometime and check that PH also.

The light should be full power and at the right distance. You should be able to measure the temp at the top of your plants. Putting a thermometer in direct light will give false readings, best method is a IR thermometer, get one for 10 bucks off amazon or ebay. Or if u cant do that just put ur temp probe in the shade at the plant top level and get a reading then. Adjust light accordingly.

Ok extraction is very important. Heat will VERY QUICKLY build up if its not getting sucked out.

Hang your filter with fan attached to filter at the top of the tent, then attach ducting and vent to outside the tent, preferably another room or outside so the hot air does not get back to the inlet vents.

There is other ways to set up the filter and fan but if the fan is directly on the filter there is no chance of smell escaping. The ducting I have has managed to get lots of small holes in it, that is why I must have the filter on the fan so that all air escaping the via the ducting is already cleaned by the filter. I vent my hot air into my attic so there is always cool air entering the tent.
