Cal/mag deficiceincy or nute burn... not enough info here... found in dumpster when, where they recently transplanted... what type of medium. whats your waters PH.... How often/ammount you are watering. Are you using nutes and if so how often/ what type..whats the temperature at canopy top.. More info you give the really good growers on here (im not one) the more they can help.
