Help! ive read all the posts but cant determine what my problem is

hello, and thanks for reading this, if anyone can help i would be very aprreciative. ive read all the similar posts and cant seem to diagnose my problem(s)?. i am a noob with unknown strain started outdoors in the midwest in june from seed. grown in a 8 inch round by 8 inch deep pot. i know it should have only had one plant in it but i had two females and i didnt transplant one out so it has two 2 ft plants with only couple 'colas' and undergrowth. i have them raised up to within 4 to 6 inches of the four 4ft flourescent lights( 2 cool white, 2 warm white). i am getting brown tips on the ends of the leaves and a lil necrosis in some spots. im not sure how far into flower i am currently . the soil was fertilized with miracle grow 3 mth tomatoe fert of 10,8,8 then ire fertilized about a mth ago

Probably the miracle grow. It always burnt the fuck out of my plants. Especially the time release soil. I would say flush the plant well, and get some better nutes.

Your plant could be losing some of its N because of where it's at in the flowering process. Do you have any pics of the entire plant? What I've seen so far looks good.

thanks for taking a minute to respond, i uploaded another photo. keep in mind this was just a social experiment in the beginning so i didnt spend much money setting it up. ive been learning more from my mistakes thoughout all this. but any advice and or critique is welcomed. yes i also have a couple incandescent bulbs in there as well because i was unsure if i had enough warm red light for flower

what would you reccommend for something so late into flowering?
