Plants are wilting and bottom leaves are yellowing!

These plants are about a month old now and are in my closet. I have a small fan running on low towards the tops and the lights. I was using a 300w CFL with 2 smaller 150w CFL's Previously, but i needed them for some other plants so I've switched over to a 150w hps. (Lights are running 20/4 so i can fall asleep.) The plants looked great, but recently began to wilt some and the bottom leaves are yellowing and getting some small brown spots (see picture), while the top leaves are very green and curling some. I don't think I'm over watering or have a light problem, and I'm not using nutrients, but maybe I'm just not seeing the correct signs? Can anyone give their expert opinion?

Get that plant into a bigger pot!

Did you poke any holes in your cup? Personally, I'd transplant to a larger pot. The roots need to stretch. Don't know what kind of soil you have, but that might be part of the problem too. Could mix some perlite to the soil if there wasn't any in it. You can probably start feeding nutes at like 1/4 strength if you wanted to. Again, it depends on your soil and what's in it. Your plants should come back strong though. They are resilient little mfers.

rootbound.....take it out,slice the roots where they r curled and matted,and repot into final pot.....also prob wouldnt hurt to start introducing 1/4 strength nutes

Yes all of the above + overwatering

I started them in larger pots in my garage and the pots started getting moldy from the humidity so I switched them to cups temporarily (however they've been in there a lot longer than i wanted) but they've showed no signs of new mold so that's good. I don't remember exactly what soil I got but I know it has pearlite. I also throw some hydroton on top of the soil to keep it from drying out so fast under the HPS. (from what I've read it shouldn't hurt?) I have nutes ready but I wanted to solve the yellowing problem before introducing. But thanks all, I'll have to get on that replanting asap.

Your yellowing is likely caused by it not getting any nutes. Its a month old, it is time for nutes. Theres not a lot of soil in that cup for a plant that size, so its going to deplete the nutrients in the soil fairly quickly. Give it a bigger pot and start off giving it some 1/4th nutes and things should pick up.

my friend has recently had simular problems but a week and a half into flowering.

He stopped adding nutrients and it started to wilt after the first drain.

Flushed with normal water and it perked up the next day. but the day after some of the flower branches r wilting, literally only lyk 3 out of them all, and there all fan leaves. But on those branches, the leafs near where the budsites will b r curling up and drying.

He had a fan blowing directly on it on lowest speed aswell. So really theres alot that could be wrong, he removed the oldest and most blotchy leaves but still not understanding the wilting? Because of its randomness, theres no pattern to it except when its a branch its near enough every leaf on it. When he flushed it he done it twice because he was informed to so im thinkin he over watered it after under watering it. Could it be anything to do with stopping the nutrients?

Also he is using tap water but he has been since the day of seedling and this is the first time its looked bad.

So confusing i feel for him
