Here are some pictures I took today of my plants.

What do you think is wrong some of the bottom leaves? Not only are they yellowing but also some of them have large brown spots! I think maybe its because I foilar feed them a week or so ago and the nutes burned into the leaf because of the heat from the lights, but I dont know... Any opinions or advice is very welcome. :thumbsup:

They are in day four of flowering. From everything I have read, I am guessing I will be able to tell sex in a few more days. I can't wait to free up some of that space and some of those rays! :stoned:

Thanks!
