First time Grow - Very Budget

Hey all, I decided to try grow my own and went with the way my old man used to do it which was plant the damn things and just water them till they were ready. Now I done a little bit of research before I started and realised it was a lot more complicated then my old man let me to believe. Im running two 2500 Watt LED Lights I bought online (China) they seemed to work wonders for my seedlings but I dont think their are putting out very much light they seem to be doing okay so far but Im worried they arent going to be enough for flowering. I have started to experience drooping of the leaves I have been away for the last 10 days and had someone watering them for me I think they may have over watered my plants. They have also grown exponentially in the last 10 days, They are currently 30 days from sprouting out of the soil and their are crazy leaves everywhere which I think may be blocking the light from reaching some of the other branches of the plants.

Ive not used any nutrients other than some Guano I had lying around in the garage for the entire grow so far and after doing a lot of reading I've realised that I should of been feeding them from the start im just looking for any advice and feedback as this is my first grow on my own with no help and after doing a lot of research ive noticed ive made many mistakes already just trying to avoid making any more. Im looking at getting the equipment to test PPM & PH in the next week and am going out to get some nutrients for them tomorrow. Ive attached some pictures.

Thanks
