Hey all, first post here, I'm trying to be as informative as possible to make it as easy as possible to help. The problem is the small size and yellowing especially of lower leaves in my grow. the leaves seem to be all prouting very close together too, and folding upwards towards the light. Any help would be appreciated. Is this a nutrient defficiency? Too hot? This is my first grow and I don't have a lot to spend, hence the skimping on exhaust fans etc.
