who wants to help a new grower, problems?

hey, new grower here. I have an indica I've been growing for 46 days in the veg stage. It's about 12'' tall. The bottom leaves started to curl, then yellow, and I'm assuming fall off next. I assumed/hoped that it was due to lack of light penetration. But a leaf or two up, I think I see brown spots developing in the green part of the leaf, though it is also curling and probably will soon yellow. Any idea what my problem may be? I'm growing in a space about 1.5'x2'x4.5', I have two 75 watt tube style cfls and a 65w cfl on the top side of the plant, and I recently added another 75 watt tube cfl vertically for some side lighting. The soil is 1/3 perilite 2/3 MG potting soil. No nutes except molasses water once a week (dont bash on it, I just decided to try it.). Maybe any ideas or solutions to my prob? Or is it a problem at all? Of course, any good advice I will +rep.

Need a photograph.

Could be many problems and you will get different answers from everyone. You need a photograph so we can look at it.

With that said, sounds like a nute deficiency but I could be wrong.

Also, you do not tell us the direction of curling the leafs are exhibiting.

If the leaves are yellowing at the bottom of the plant, then getting crispy and falling off, then the plants probably need some more food. I had the same issue on my first grow, and I just needed to up my nutes a bit, and they were already in soil with nutrients in it. Indicas can take a lot more nutrients than sativas before they burn.

Search up "nutrient deficiency table" on google and click on the first couple posts. Basically see if you can diagnose your own plants. And also upload some pics, they help a lot!

thanks guys, unfortunately due to a lack of technological instruments, I can't post any pics as of yet . But I will definitely check out that table. And it starts at the end of the leaves, they first start to curl at the tip down and inwards towards the main stem. The rest of the plant looks great, but I figured if not light penetration then it'd be a nute defficiency. But I just two or three days ago put my plant in the MG potting soil, which has an NPK of like 20-9-7 should I wait and see if the soil helps? Or go for the nutes if it turns out that's what I determine it is?
