help me

hi everyone my plants are goin yellow and brown i wondered if any one could help me ill put some pics on to show you please help!!!!

by the way it looks it might be nitrogen deficiancy.. but i cant tell how old the plants are or what stage there in the pictures are hard to read

looks like your in a spot of bother there man.. its either one of a few problems nitrogen defiancy, bug problem, root bound?? so id go about it like this just to cover all you bases.. go out and buy yourself some quality nitrogen enriched potting soil, put it in a much larger.. as big as you can find pot.. make up a soap spray and after transplanting spray all of the leaves top and bottom with it.. tell me how it goes.. and i have a few bug repelant and killing recipes if your interested.. good luck

Its almost definitely lack of fuel...nitrogen being the principal one. Your pots are way too small as well. Your babies have simply outgrown their environment. Take action now ! Bigger pots, ferts, TLC...your plants are dying of neglect.
