Auto northern lights 4th week flower ! take a look

here is my Auto northern lights which is currently in its 4th week in flower, the buds are starting to come out and are showing signs of crystals on the buds. also, the leaves around some parts are turning yellow, i plan to start giving pk 13/14 to it in a week or so to add flavour to the buds.


please can you give me an estimate of yield if possible and how long there is to go for this plant...

keep updated as i will post updates of this plant regularly..
