Sunburn. Spiders eat bugs. They don't bite plants. Your friend might have meant spider MITES though. Actually the bugs we are concerned with are 2-spotted mites but if the damage looks 'speckly' you should immediately treat with a light mist of gardensafe fungicide 3. It's at any box store in the garden section.
stinkyattic Reviewed by stinkyattic on . White leaves/spider bite/sunburn? We have recented moved some White Whidow plants outside in the sun and they have had days solid sunlight , and the leaves have turned white. The plants look healthy , but the leaves are really white , my friend seems to think this is spider bite...Do spiders attack cannabis? Also i have another post and another user kindly suggested it was most probably sun burn , as i put them out into direct sunlight too soon. Spider bite or sunburn , whats the verdict? Thanks :wtf: Rating: 5
