New Growth probs

Hi, I am having some trouble with this new growth, the causes may include lack of air (no fan or good ventilation) not enough Nitrogen, place where I had them too small, maybe bugs. Sorry to ask like this but a friend was watching them until recently , he didn´t do the best work but plants are alive and flowering I just wanted some advice on how to take good care of them from now on, I am posting some pictures, thx a lot for helping!!!
Cheers!

check for mites. let it dry out. get a fan on it. re-assess.

my first thought was spider mites!!! check for those 2 spotted buggers under the leaves, they will be VERY small so look very closely.

How warm is it in the closet?

Look under the leaves for bugs. They are tiny. Get a fan. The close up is too blurry to see alot.

The closet is cool, temperature must be around 20 (celius) and I do have a fan now....about the bugs what´s the best way to proceed ? never had bugs before so no idea if I should just remove them myself or get a nice bug killer. Thx !!!

i hear good things about Mighty Wash. i use neem, hot pepper, and garlic. i never get rid of them........but, they never overwhelm my grow. perpetual war.

Fruit tree spray will help...its a little late

Thx everyone but I was hoping to get more nutrient/soil facts info ....more N or F , less or flush kinda thing. Grandpa 149 I said 20 celcius degrees which is about 70 Fahrenheit, assuming you are talking Fahrenheit here the temperature is no more no less than happy, and I said have a fan already, any more ideas? I really want to get something out of this even though I know its late and they are hurt bad. Thx a lot!!!

Shoot for 75* daytime (lights on) and 65* night (lights off). A 10* drop in temps at night is optimum.
