OK where did I go wrong

I live in a very high humidity area. Its very warm and perfect place to grow. I planted my seedlings in August 1 its September 30th. They are indoor plants... NOW after 2 months they are only 12 inches tall and seems like they just wont grow anymore. between the branches there are little leafy hairs, are they males or females? I burned 1 a little bit.. The other has curling leaves at the very top of the plant. I've been watering every day only because the soil is extremely dry all throughout the soil. BOTH of the plants have yellowing at the very bottom of the plant on the last two leaves... Im not sure what it is. Please help why arent they growing? Ill post picks soon if you cant figure it out.

if they are flowering, then they stop growing after the initial stretch...
The curling leafs at the tops are probably from heat stress

Every day watering indicates to me that they are rootbound, how big are the pots? Contrary to popular belief MJ plants do not like very warm environments to grow in. temps between 70-80F are ideal, anything above 85F and the plant will slow growth to a crawl.

Pictures would help immensely.
