Somthings wrong with my plant!. Please Help.

I hate to ask a noob question like this but i have no idea what is going on.

I have four plants still growing. One of my plants which is about 2-3 weeks away from harvest has started to look a bit sick.

The whole plant seems like it has lost alot of color its yellow and some places its pale green where as last time i was in there it was nice and green. Also the leaves are drooping as if it is being under watered which is not the case. All of my other plants are still really green/purple and are doing great its just this one plant.

I just fertilized and watered on Wednesday with a 15-30-30 fertilizer mixed with 2 table spoons of mollasses. As i usually do. It is Friday now so its only been 3 days.

When I checked them today all the soil was still nice and moist.

The thing is today we had a light frost and its been windy. I have them all tied up so the wind does not really effect them but i am thinking that the plant may have been hit pretty hard by the frost. All my other plants are fine but this is the only thing i can see that would actually explain what it going on.

Does anyone know what is wrong?.

If you need i can go out and try to get some pics.

well, pics are always good, but i honestly just think its the natural yellowing of the plant. towards the end of flowering the plant uses up its nitrogen through its leaves...resulting in some yellowing. check out dankohzee's grow, he has a trainwreck plant that is yellowing. look at it and get back to me if its something similar- totally normal.

Plants do occasionally just curl up and die for no obvious reason. And plants do get some deadly viruses and pests, which do not become obvious until the damage is done because they attack the roots first..
I think to be safe I would take it away from the others.

I checked out that grow and mine seems to be much worse. It went from being nice and normal and green to the pretty much the entire plant turning yellow in 2 days. Im thinking im just going to let it do its own thing for a while just in case it was the frost that made it happen. It wasnt a really bad frost but i watered them 2 days before so it probably got pretty cold.

Thanks for the help guys.

Are these plants in the ground? You may be over watering. This would cause the droopy leaves just as bad as under watering. The yellowing is probably just the end of the plant's life cycle. I've been growing outdoors for years. Some plants yellow, others don't. Also, you should quit using fertilizers at least 3 weeks before harvest. Your buds will taste much sweeter. Good luck and have fun with your harvest.

No these are in grow bags. I only water once a week unless i think they need more or it rains. I am going to start my flush next week on my one plant. Always a sign of mass amounts of weed comming my way soon time . I am going to take some pics of this plant tommarow in comparison to my other plants. Just to give you an idea. I would now but it is to dark
