Little small white spots on marijuana leaves?

  1. Hey everyone, my plant is about 5 months old - growing outdoors in Australia, it is about 3 weeks into the flowering stage now and I have just begun to notice that a quite a few of the leaves are covered in these small white spots. It is mainly the lower and smaller leaves that are affected - the leaves higher up are looking very healthy. I fertilize it once a week with MiracleGrow Flowers and Bloom and liquid seaweed fertilizer, the weather here is quite humid and hot, the buds and everything else seems to be growing without a problem I just want to make sure it isn't a sign of any serious problem, do you guys have any ideas/suggestions? thanks!

  2. Looks like bug problems. Look under the leaves do you see anything?
     
  3. Yes. Little brown or black dots that are tiny. This is my first grow... How to cure??

  4. there bugs mate. if your outside more likely youll get them and they will just keep coming just make sure theres no likkle spiders under the leaves looks like small black dots of pepper tht move if you do find its spidermite but they look like thrip attacks
     
  5. youll see little worm/maggots tht are yellowish and very tiny moving i cant really suggest other then ger a organic pesticide and keep on top of it they will be ok
     
  6. could even be leafminer but i never had this before so not 100%


     
  7. I'm with picklepeppers. Looks a lot like thrips. They start out like tiny white maggot looking bugs and mature into tiny black bugs. They have a long thin body compared to spider mites. BTI (Bacillus thuringiensis israelensis) is a good safe way to control them. Allthough, you should check to see how effective it is outside. Another good safe one is Spinosad.
