Yellow/Brown leafs ????

Should i Rip them off ?

theres no need to ever rip off leaves as they play a major roll in how and why plants grow...u have a def. what def. however is something u will have to research on ur own. the plant is deficient in a nutrient which is causeing the plant to search for these nutrients in itself. u may want to take into consideration, soil, temps, lights, airflow, nutes, ph, etc.
